Engine Performance problem
1995 Chevy Astro 6 cyl Two Wheel Drive Automatic 131000 miles
my astrovan is giving me fits. When driving at a normal speed it purrs like a kitten. When I give it gas to speed up it starts sputtering like its missing on a cylinder. This has been going on for a week now and I have done everything I know to do.
the diagnostic codes show it needed a IAT sensor. I replaced it today and to no avail. It still does the same thing.
When it is cold (first start up of the day) it runs great til it gets warm(about 2 miles). Then it starts. As I drive farther it also sputters on start and start.
i have checked the plugs, wires, cap and rotor and all are fine. It is getting great fire. I replaced the fuel filter thinking it may not be getting enough fuel. Didnt help. I replaced the IAT sensor and no help there either.
any help will be appreciated.
have the same problem?
