Hi: I have a 1990 Iroc with a 5.0F TPI, manual trans. With about 130,000 kms. The car runs great when cold but after about 15-20 min. Of driving it starts to feel like it is misfiring or running on 7 cyinders, then you shut it off and it will not restart, cranks over fine but will not fire. Once it has cooled down it starts and runs fine till it gets hot.
have the same problem?
