Can anyone recommend a shop that specializes in our 3rd gens? I have a surging problem with mine that I'm sure is just 3rd gen related and I'm getting tired of all the shops out here "guessing" what the problem is and not fixing it but still taking my money. Anybody have any shops they can suggest? I'm in ventura county, but will make the drive for a good shop. Thanks.

Someone on this board might be able to help you, but we need to know the year, and type of fuel system. Carbs are different than fuel injection, tbi is different than tpi, and 90 -92 speed density tpi is different from 85-89 mass air flow tpi systems. You probably mentioned your car in previous posts, but some of us have short memories.

Excellant recommendation Russ, I know I had a TBI 305 RS that used to surge as well, until I replaced the EGR Vacum selenoid, which pointed me to a bad EGR, for example

I know all about short memories, ask the wife.
The car is a 91 Z28 with the 5.7/auto combo. Completely stock. Had this problem for a year or so, just getting worse. Replaced the computer, computer chip, some other related stuff over the past year. Problem still exists. Just getting tired of replacing parts that mechanics say "could be the problem", and not solving it. Thanks again for your help guys.

Have you cleaned the iac?

I don't know anything about these cars. I build "old" hot rods. What is the IAC?
