MAP Sensor Maybe a bad MAP sensor ????

Update to my idling problem I installed a new ECM (reconditioned) now the check engine light wont give a code, its continuously illuminated. The idle problem is gone. When I get on it on the highway, it goes up to about 4000 RPM or so and starts to backfire, but when I let off the gas, it...

Also, I have sprayed carburetor cleaner in the carb, and that has happened (the correct idle and all that. I'm not Mr. Goodwrench, but im gonna bet its that damn carburetor gasket. But please, keep the help coming!

I have noticed that when I start it, initially, it runs ok... then once the RPM's drop, the engine starts to shake and idle's about 300 RPM. I'm going to check out the carburetor gasket. Would a carburetor gasket do this also ??? I need to get this fixed. Not cruising in my vette is horrible...

Hiss... I have noticed that a hiss is coming from the carb, when i take off the air cleaner, but I'm figuring that its the carb sucking air for the mixture. Who knows. I really havent seen a problem stopping the car, the brakes work fine to me. dont know... still at a loss here. i havent...

? Although... The fuel pump was replaced a few months back, maybe it went bad again???

What i've done so far... (ATTN: Sensei) Ok, here's what i've done so far. Replaced the fuel pump, checked for vacuum leaks, replaced fuel filter, cleaned carb, looked over carb (which was rebuilt one year ago and seems to be operating correctly), replaced fuel lines, vapor lines, dropped and...

The other day im out driving my vette, and all of a sudden when I took my foot off the pedal, the RPM's dropped of course, and it started running choppy. I pulled it into a parking lot and stopped. It idled like crap. just under 500 RPM. When I gave 'er gas, it ran fine, but when it came back...

I was at a red light the other night, and I decided to take off from the light. I tromped the gas pedal and took off. Is it normal for first gear to take so long to shift out of? Once it hit the red line, and hit second gear, it REALLY took off, and runs great, but it seemed like a hell of a...

I was out the other day, and was just messing around and thought of setting the cruise control... i set it, at about 55-60 mph, next thing I know, the thing takes off, and im doing 70....75....80, and keep climbing. I freak out, thinking the accelerator is stuck and thought I was gonna die...

I am obviously planning on gutting my 81 this winter and restoring the interior. I only have a couple of questions and maybe you guys can help me out... 1. I noticed that when I put my passenger side window down (power motor) my door lock moves. 2. I'm planning a total overhaul of the...

I recently took my 81 to NTB for an alignment and of course new rubber. I had asked for a front and rear end alignment (since the guy probably didnt take care of this issue either before I bought it) SO... I go to pick up my car, and the guy at NTB says that he couldnt do the rear alignment...

when i first bought my 81, the gauge read 40 for the oil pressure, seemed fine. now the gauge jumps all over the map from 20 to 40 to 80 to 60 back and forth. I'm wondering if the gauge is bad, loose connection, or a major problem. I have ran the car and It still runs great. no problems that I...

On my 81... I see that the guy who had it before me has a welded bolt through the lower valance. Thats not supposed to be right? It looks like its a half-assed deal and it does not belong there. Does anyone have any instructions on how to correctly install this piece? (its the piece that the...

On my 81 I have noticed when i crank the motor over to start, i hear this sound like a low speed crank siren or something. I really cant describe it to a "T" but thats the best I can describe it. Anyone know what this could be? and if so, is it harmful, or something about to blow? or need...
