I just got done putting a ls vtec in my 90 integra and on the pgm, there is olny a place to plug in one or the other..
Either the regulator control solenoid valvle or the purge cut solenoid valve, the are the little black things next to the map censor, the regulator is the one on the passenger side and of course the purge is on the driver side, does anybody know what one i wanna plug into the fuel manifold, or do i wanna just splice them together, i have the regulator pluged in right know the car seems to run fine, but is that correct?

What simple way to determine whether fuel injector is spaying gas or has a bad valve.?
Spark plug is firing. Fuel injector lead shows electrical charge. Compression is at 130. One mechanic says the fuel injector is the problem because not spraying gas. Other mechanic says fuel injector is spraying gas. Says the problem is a faulty valve. It appears that both are guessing. Fuel injectors cannot be taken out unless you take off the head. How do I decide which is the problem. .

Simple. You can get automotive stethoscope like this
http://www.sears.com/shc/s/p_10153_12605...
or just use a long stick. Touch one end of the stick to the injectors and the other end to your ear. The sound should travel to your ear. If all the injector are firing, they would all sound about the same. The dead injector will sound muffled or nothing.
But that only says that the injectors are opening and closing. It could still be clogged. In which case you should at least try fuel injector cleaners.
Good Luck...

That last one was a good answer! The only thing I would add to that is .. it seems like you had a compression test done because you report a 130 lbs figure, and that sounds nice and high. Are all of the other cylinders +/- 5 lbs off from that 130 number? What I am getting at is if you had a bad valve (leaking or bent, not seating properly, etc) then the compression will be lower for that particular cylinder.
So maybe you can rule out half of the equation right there. Of course you didn't say what model/year the vehicle was so we don't know if you can use a cheap Harbor Freight ODB-II code reader (just $39 and SO worth it), which might tell you the EXACT problem, right down to which injector is bad.. or if you're not burning all the fuel in X cylinder.
As the last gentleman recommended, buy a couple bottles of injector cleaner and dump them into your $80 full tank of gas.
Reply:fuel injectors can _ be removed from the cylinder head_ separately, fuel spray patterns can be checked buy any technician with suitable test rig. the compression looks ok!
Reply:One thing you might try is running your engine with one f.i. disconnected electrically at a time.
Either way, they're saying they think you have a bad injector. That might help to show if you do.
You didn't say you took your car to a mechanic.
Reply:if it has compression the same as the others it is not the valve, you can swap over 2 of the in jectors and see if the problem is the injector, then it would mis fire on the cylinder you swapped it to

I recently had to buy a new Goodyear Eagle RSA for my monte carlo ss and was wondering about the cost?
seemed like $236 was high! Why are these tires so expensive??

if it was 236 each you got bent over and there was no lube used but if it was 236 for the set you didnt get off to bad i just put tires on my truck and they where 175 each so dont feel bad
I recently had to buy a new Goodyear Eagle RSA for my monte carlo ss and was wondering about the cost?
Goodyear cost tony Stewart from thee wins this year, the tire's are just not cutting it, better tires are Firestone they won the Indy 500 this year(they were the first tire at indy) and , Uniroyal, Yokohama all good brands, Goodyear is over priced and over rated , , They cost more because your paying for what they have brainwashed people with as the best tires , they are ok, very far from being the best. There are well all brands sold in America must pass the D.O.T. Department of Transportation Regulations, to be sold in America, so there are cheaper tires with names you never herd of ,that are equal or better than Goodyear, fact, I have a Indy 500 Fire Hawks on one truck,(same compound as the Indy tire but treadled, and Uniroyal on the other, and Michelin on the other , they all have the same guarantee,you can go to any big tire store and ask them for the equivalent tire that of good year and buy theses you will be just fine , I have been doing this 30 years, there used to be a tire at pep boys called Torque Twisters, they quit selling em in the mid 70's cause they did not wearout, and in 1980 toyo tires were cheap but same rating as the equevelent tire sold hundreds of em, no one heard of em now its a top brand big as goodyear, also sam winston sold the best tire for the money , Winston Tire Lifetime warrenty but when he died they closed and sold out but I dont know to whom, best bet , Go to wall mart they have all name brand tires, all four profesionaly mounted with the letters out ,or black wall, or low pro, and it will cost you under $300.bucks, and free rotation when needed , same with costco and sams club. Sams club is owned by Walmart, hope I help you good luck.
Reply:For that particular tire for that particular car the price is about right.
Why are they so expensive? Why is the car so much fun to drive? A lot of that comes down to the tires which in this case are big, have a high speed rating and very low profile.
Personally though I am not a big fan of the RS-A. I think there are a lot of tires out there that do as well or better for a lot less money. A Firestone Firehawk GT for example is probably a better tire for around $100 less.
Something to keep in mind for the next set. These don't last long anyway.

Why does it seem my 4runner guzzles gas! (please dont say gas prices)?
I drive a 1994 Toyota 4runner! I know its known for low MPG. I think I get about 10 MPG according to http://www.fueleconomy.gov/
What can I do to get better MPG? Repairs? Tweaks? The idle is very low. What causes MPG to decrease?
my husband and I think I get less than 10 MPG. He's gonna make me sell my 4runner for a more fuel effecient car. HELP!!
Why does it seem my 4runner guzzles gas! (please dont say gas prices)?
Don't go chasing bad MPG unless you are sure of it. You could be spending time and money chasing ghosts. So try this experiment first:
(a) fill the tank to the max
(b) get on the HWY - late night / no traffic hour
(c) drive about 20 to 30 miles (at 55 MPH)
(d) use cruise control - very important
(e) note the EXACT MILES
(f) get off and immediately get gas
(g) note the EXACT GALLONS
Now you can calculate the MPG by
MPG = MILES (step e) / GALLONS (step g).
The reason you start out with full tank is that is the "repeateable" condition. You want to avoid traffic so you don't use the brakes on the HWY. Braking will negatively affect the MPG calculation. You use the cruise control so you and eliminate your driving habit as a factor.
Without a good MPG calculation you might be wasting your money chasing ghosts. Also you can repeat this test anytime you feel like you car is not running right. You can also try the same thing but off the cruise control to check how much your driving habit affect the MPG. etc.
====
There are few thing you can do to save (or maximize) gas MPG. First get a tune-up.
(1) spark plugs
(2) spark plug wires
(3) distributors, coil, rotors (if you have them).
(4) new air filter
(5) PCV
(6) correct tire pressure
(7) clear the trunk of useless heavy items
(8) spray clean MAF sensors
====
Forget all those "SAVE GAS" scams. This was on NBC morning TV show. The difference is as much as 38% (their claim). There are very simple rules to save gas:
(1) drive slow - not too much past 55
(2) accelerate slowly
(3) don't brake unnecessarily
(4) use cruise control - whenever it is safe to do so.
Don't coast - it is NOT safe and it does NOT save gas.
The above really works. Using those simple rules I was able to drive from Boston to NYC (210.5 miles) on just 5.112 gallon (94 Civic). That's 41 MPG (94 Civic 187K miles). Actually I was speeding at 72 MPH so I could do even better at 55.
WOW !!
===
Compare before and after MPG using the first set of rule any time you think your MPG has changed.
Good Luck...
=== UPDATE ===
One greatly over looked sensor is the WATER TEMP sensor. If this sensor fails, the computer constantly think the engine is cold (forever) and runs the car in RUN RICH (extra fuel burned) mode. And to top it off, the great check engine light does not even come on (because in the extreme cold it really does take forever to warm up - and this is a correct behavior but only for extreme winter).
Why does it seem my 4runner guzzles gas! (please dont say gas prices)?
Heavy truck, small engine, the engine has to work harder to get the car moving.
Reply:It's a V6 i take it..Petrol 4x4's tend to use between 15 and 20 litres per 100km / 60 miles. I know petrol patrols use 20L and my dads v6 pathfinder uses 17L. My diesel 4x4 uses around 10/11 L / per 100km. You could convert it to LPG which would cost a couple of grend but fuel is about 1/2 price
I did an experiment the other week, Every time i came to a down hill or could see it was stopped far ahead i wacked it into nuetral and coasted.(DO NOT TRY IT IF IT IS AUTO) I managed an extra 100km out of my tank. It is not a good thing to do long term as you increase wear and tear on just about everything.....
Reply:OK the 4 runner that you have has a 3,0 V-6 right ? good truck, but its a heavy vehicle and you need to really give it the gas when your going on the freeway , the 1994 was a good year, but fuel was cheaper ,then, I like the 4 runner well built, but poor fuel, you can buy a new 4 runner and get great power and and great fuel millage, 14 year sine that was built they have come a long way sounds like to me you still like the 4 runner feel, so stay with that type of truck ,cause a Chevy 3/4 ton four door long bed brand new gets 10 miles to the gallon, now that's with all the bells and whistles, so don't go that direction, I would go to the ford dealer and test drive a sport track or a freestyle all most 40 mpg 4x4 and east to drive and 100,000 mile bumper to bumper warranty, and very powerful more than the Toyota, and better on fuel, buy American keep it strong
Reply:I can't offer you any help with your current vehicle, but I live in the UK %26amp; we have 4Runners over here, as well as a lot of Japanese import Toyota Surfs. In the UK, we pay a terrific amount fo fuel, so these vehicles tend to mainly be diesels, and I know the Toyotas are considered heavy on fuel here too: The UK vehicles are 99% manuals, but the imports are mainly autos, and I know the average for a diesel auto is around 20-24mpg.
If you like the car, look for a diesel: I know they're not common in the US, but I feel they'll become a lot more so as your fuel prices go up.
Performance wise, turbo diesels offer a lot more low down power: If you can afford a newer one, their performance is fantastic - I have a 2 litre turbo diesel Vauxhall van which is much, much quicker than my 2 litre Honda Accord VTec.
ps Today, we're paying $10.00 a gallon for petrol %26amp; $11.31 a gallon for diesel.
Hope it doesn't come your way too quick!

I got this board at the royal show . Is there anyway i could get it to spin for longer
How come my wheels on my skateboard only spin for 10 seconds (its pretty old but its not rusted or anything)?
Yes - apply some spray lube. Lithium grease would be best but even WD40 would work.
You can get lithium grease at any auto parts dealer. You can get WD 40 eveywhere (sears, homedepot, autoparts dealer,etc.)
Good Luck...
