    To buy or not to buy???

    A friend of the family has an 88 convertible with the 4+3 for sale. The odometer "reads" 6K. He is the original owner and says he has had an intermittent problem with the odometer not working. He feels the car has around 10k on it. The car looks and drives like a 10k car, and he is asking...

    Vacuum Problem

    How about an intake manifold leak??? Put the vac guage back on, watch the guage and snap the throttle. If pressure goes down your ok...if it goes up I'd check for a internal leak.

    MAF sensor relay help

    Thanks Vig... I'll try the ECM clean out sometime this week. Can I just pull the neg off or should I pull both terminals? I've been told 15-20 mins disconnected is long enough...do you agree? While I got you... I'm replacing my bilstein's this week and was wondering where I could find some...

    Oil filters

    I have also had and heard bad things about the fram. I had one leak around the no-slip coat they put on the end. Don't know how or why but it leaked. I use the mobil 1 filter. Never had any problems. I order them online directly from mobil.

    Octane question

    I saw the same thing in my 86 manual and also ran 87 for a long time. I also would run some injector cleaner through the system twice a season. I started running 94 because my friends told me if I drive a vette the least I could do is pay 20 cents more and run the good stuff. I noticed no...

    MAF sensor relay help

    I hope I didn't open a can of worms I put the two relay's in as you said (nice detailed description, thank you), and started the car. I started a little hard, but no check engine light came on. The tach read a steady 700, which is normal for my car, but the idle was very "lumpy", like I put a...

    MAF sensor relay help

    Still need a little help... I got the two different relay's but I can't tell which one goes where. The power and burnoff relay's look the same. Both relay's have 5 pins, but one plug has 5 pins and the other only has 4. Does anyone know how I can tell which is the power and which is the...

    Exhaust Systems

    I just spent the big bucks on the borla system from the cat back. They look and sound great. They have a deep sound, but are not over-powering. The only complaint is the two hours it took fooling around with the mufflers to get them centered evenly.

    86 EGR tube

    I'm replacing the heat shield on my 86 EGR tube and there is a clamp on the bottom of the pipe. Does anyone have any suggestions on how to squeeze the clamp tightly. I called my local chevy dealer and they said there is no special tool, but other than that they were no help.

    MAF sensor relay help

    I decided to change the MAF power and burnoff relays on my 86 vette do to a hard start condition. My local dealer sold me 2 with the p/n 10067925. I put both in and the check engine light came on and the RPM's were all over the place. As soon as I put the old ones back in the light went off...

    Throttle Performance Switch

    I was on vacation in FL and talked to a guy from Ecklers about these switches. He said "push your foot down farther and you'll save $100 bucks" So I blew the money on two shirts.

    Gas in Oil

    I would keep an eye on it. It could be somewhat serious. I would want to know why the mechanic thinks there is gas in the oil. Did he see it? Did he smell it? Was the level on the dipstick high? Is the car running rich? My guess would be a fuel injector leaking. The only way I know of to...

    Trans fluid question

    A good friend of mine has a 1986 coupe with 72,000 miles. He wants to change the trans fluid and has some questions. The fluid is not burnt or dirty this is just maintenance. Do you recommend a flush or to drop the pan? Regular ATF or synthetic? What brand? How many quarts? Any advice will...

    vacuum switch question

    I'm currently having some mild engine work done on a 1978 L82. My mechanic thinks there should be a "vacuum switch"(maybe incorrect wording) in the thermostat housing. My local chevy dealer can only find the part for a 1979 & newer. I think my mechanic might be describing the part wrong, or...
