Question about 1995 Chevrolet Corvette
Have had the throttle body replaced, ECM replaced, spark plug wires replaced. Had fuel pump and filter checked. When I take it to the dealer they put it on the computer and do a scan and can find no problems.
If the moisture goes to your distributor which is sitting right under water pump,or the vacuum line that goes from it to intake manifold is plugged and not sucking moisture and some harmful gases that being crated inside distributor,causes rust that ruins your distributor
and it is pain in the you know where to change it
assuming you already checked the fuel pressure,(42 to 47 key on engine off) and about 55 psi when you take the vacuum line off the fuel regulator( it is located at back of intake manifold driver side)

You could check and see if the cattalitic converter is clogged. My friend had the same problem with his 92 Corvett

Have you changed the fuel pump yet?I had the same exact problem.I replaced my fuel pump with an AUTOZONE PIECE OF JUNK fuel pump.That pump lasted almost 2 days.The second day i had it the truck didnt want to start but it did and it ran like ****,and when i put it in gear it ran as long as I didnt touch that gas pedal.You could go get a fuel pressure test or just replace it,your call.You might want to check your filter too but im sure its the pump.Good luck

Please go to the crossfire injection forum to get some straight answers to the 82 corvette CFI system and how to troubleshoot it properly. There's a lot of misinformation given here, so much so, I don't know where to begin.
One thing is, the 82 corvette CFI does NOT have a MassAir Flow sensor system, it uses MAP and O2 mostly. The CTS sends a signal to the ECM telling it what the temp of the motor is and in turn the ECM controls the amount of fuel being dumped. On the older (orignal) CTS sensors, they have one wire and takes its ground from the threads. If any coorosion takes place, usually the CTS will report a cold engine and request lots of fuel.
To repair this issue, install one of the newer style CTS sensors that have two wires, one for signal and the other is ground.
Fuel pressure and vacuum leaks on any CFI motor play key roles. Set the FP to 14-15psi measured inbetween the TBs. The regulator is located on the rear TB and must be slightly moded to make it adjustable and can be done in a few minutes.
