blue iroc

I've decided to start another thread in the hopes that someone can help me.
My 89 l98 tpi iroc starts quicker without problems when weather is really cold. Once the weather gets hot the car car struggles to to start. In hot weather I have try to start it 3 times
before it starts. Iroc sputters and dies. Its as if it flooding, smells a lot like gas. Once it starts warming up the iroc runs great (hot weather). Keep in mind it only happens in warm to hot weather. Throttle response and idle are awesome. Someone please help.

Thanks in advance.

My L98 does the opposite. Struggle cold, runs great when hot.

Something temperature related ... I too did the CTS, no change and the only sensor I didn't change was the IAT (intake air temp) under the plenum of course.

Didn't see that on your list.

Thanks for replying. Is the iat the same as cts? If its not the same where is the iat located?
