I searched for this topic but found nothing...
I am looking for someplace to bring my 1994 z-28 conv for repairs.
I am new to the seacoast of NH and have found decent mechanics, but none with much expertise with my gen 4, and I this spring a problem has arisen three guys in the area are unable to figure out.

In May the car started cutting out while driving. Usually at the point it got warmed up, a few minutes into starting it in the morning. It would roll to a stop and start right up and I was fine for the day. As time when on it got worse in that the starting became harder, I had to wait, it would wind, I would have to try several times.

The mechanics tried several things, but with no joy. Coil has been replaced, coil module has been replaced, the coolant temp sensor and wire to it as the wire was found to be frayed, so replaced. Throttle body plates cleaned, MAS cleaned, etc. The opti distributor was replaced a couple of thousand miles ago, but 4 or 5 years ago, so they figured it was okay, and probably would not cause he cutting out. You get the idea.

Where should I bring this car? People who know and work on Gen 4s.
Lowell, Lawrence, Nashua, Portsmouth, else where?

Thank you.

 

Thank you.

 

It starts up fine in the morning, runs great for about 5 minutes, then cuts out. Restart can then be hard and engine might, but usually runs fine.
Thanks for the help.

No codes
Thanks for the ideas
