I have a 1985 Corvette with 166K miles. It ran perfect despite the fact it uses a quart of oil every 600 miles. I had the hood painted and the body shop allowed a lot of stripped paint residue to get inside the engine compartment. They then powerwashed the engine without asking me. I picked the car up and it was missing very bad. I thought I had a fouled plug. It did not. The body shop agreed to pay for all of the repairs. I took it to the local Chevrolet dealership and two different mechanics could not figure out the entire problem. It runs much better; however, it still seems to miss or make a different noise when it is cold. When it is warm it seems to run perfect. It has a new distributor, distributor cap, rotor, custom sparkplug wires, spark plugs, coil and radiator fan switch. They checked compression, engine codes and the electrical part of the injectors. Also, I have used an expensive 2 part fuel injector cleaner. Do you know why it still sounds like it is missing when it is cold and at lower RPMs while driving? It does appear to have a hole in the right exhaust. I coated it with some high-temp metal repair. It didn't help. I keep thinking it is a sensor. Thank you very much.

I installed a new factory mass air flow sensor and no change. My car only runs poor when the water temp is below 150. If it is warm it runs great. No codes are in the system other than a burn off module. The burn off module code has been coming on for years. It hasn't made a difference in how it runs. I cheked the voltage on the TPS and it is fine. Any other ideas? Thank you.
