2001 Chevy Astro Van idles rough when stopped in gear. But not in neutral (
My 2001 Chevy Astro van idles and vibrates rough when braking to come to a stop, and while stopped (in gear).
But if I slip it into neutral it idles out fine(?). I was having problems with my heat. So, I replaced the thermostat, flushed the radiator and added new anti-freeze. This helped to care of the heating problem; And, relieved some of the rough idle symptoms I've been experiencing.
Any ideas as to the possible problem for the remaining rough idle vibrations?
