I did it a few years ago, And I am not near my car or I would look for you. but I am almost positive I had to take the AC bracket off to make it fit. It is a bit of a PIA to snake down there, and almost always a PIA to get the nut to align properly with the fuel pump.

I agree that the ECM does not monitor any of the smog stuff, it does turn on the EGR valve and I think it controls the air diverted, but has no feedback from any of the smog stuff. It seems like you have done a good job in sealing all the vacuum leaks, which is time well spent, but it still...

I have owned my 81 for over 30 years and it has always "squealed" when driven in reverse. I have heard others describe the same thing. Hasn't bothered anything else in all these years, so I just consider it one of the many little idiosyncrasies of the beast

The 1981 is the first computer controlled corvette. ECM is the Electonic Control Module, or simply the computer it is located in the battery compartment behind The driver seat. It will be on the front wall of the battery compartment. It is a silver box about 6" x 8" x 3" with two...

Do you know if the ECM is still in the car? That is very strange behavior. If you do have an ECM, do you know how to read codes? If so, are there any codes? If not let me know and I will tell you how.

Well, It is a 34 year old car, made when the quality of american cars had a lot to be desired!. So it will probably leak, drip, ooze, smoke, smell, shutter vibrate, rattle, and be too noisy to have a normal conversation -- GOD I LOVE THAT CAR!!!!!:happyanim: Seriously, change the fluids...

You seem to be curious if you will HURT the value of the car by painting it. I would not think so. The 1981 corvette is not very collectible now, and probably not in the foreseeable future. Right now I do not see the plastic bumper corvettes ever commanding the prices of their chrome...

The hinges on the seats have an inertial" switch" that stops the seat collapsing forward in a crash. It is a simple pendulum that locks the seat from moving forward. I assume yours is a little sticky and got stuck when putting the cover back on and then freed up again. Some wd40 will...

Remember that the dwell only fine tunes the idle mixture. I would not expect it to cause such a change in mileage. Again, that mileage is saying the carb is full rich at all time. I bet there is black smoke coming from the tailpipes when you accelerate. Have your wife follow you. If so...

It is fairly straight forward. Are you comfortable opening up your carb. It could be done with the carb on the car, but I would suggest taking it off. There are a lot of detailed instructions around on how to dissasemble a QJET, but I will outline what you need to do -- this is from memory...

That mileage is exactly what I expect if the ECM goes open loop (17mpg Closed loop, 7mpg open loop). This may be obvious, but is the car throwing any codes. If there are no codes, is the ECM working -- can you get code 12 when you jumper the test leads?

The solenoid doesn't actually increase the idle, it actually just doesn't let it return to normal. So if the ac is active and the throttle is open the plunger is extended and when the throttle closes, it " rests on the solenoid". It is adjusted by turning the bolt

As far as I know, the 81 ECM only controls the idle mixture. NOT the idle speed. That is still controlled by the idle speed screw

Is there any reason other than performance that you want to change out the CCC? Check engine light on? There are plenty of people that can help you fix that The CCC is nowhere near the limiting factor in performance. First is the exhaust, spend money on true dual exhausts. Then are the...

I agree, It is a 30 year old car with a cross fire injection system that not to many mechanics are still familiar with. It will need a lot of attention. My suggestion if you want a corvette for $10k is to look at the late 90's C4. They are a great price right now, much more reliable...
