engine warm string problem
MY '92 Vette LT1 w/108,000 miles is difficult to start when warmed up. Cold start no problem. I replaced the plugs and wires (WHEW) hoping this would solve the problem. It did not. My next attempt to solve the problem will be to place a injector cleaner with the fuel. Got a fairly new K@N air cleaner in place. This problem wasn't a progressive problem it came one day a couple weeks ago. Any thoughts will be appreciated. Thanks Guys.... and Gals

Another member on the forum had this same issue on a 94 last week I think. It was the throttle position sensor. Replaced it and they have not had a problem since.
He bought one for an LT1 Camaro since the auto parts store did not have one for the LT! Corvette in stock lol The Camaro one was half the price I think.

oldtimer: is it only hard to start when warm or does the engine also stumble when warm?
I assume the starter is working and turning the engine, but it is just not firing...right??
Suggest checking fuel pressure when engine is warm.
Also check spark color with engine warm.
