Cruizing problems.
Hey.
I have an 1986 Z28 Iroc with the 5.7l and i have a problem.
When i'm cruizing down the highway at 55 or 60 mph the rev suddenly drop about 250 rpm and then rizes again. this does not accour all the time.
It has an rebuild automatic transmision done in 2010 by the last owner.
