Question about 1992 Chevrolet Astro Extended

1 Answer

Van won't iddle and has no power.

On my 1988 chevy astro V-6. Running fine and suddenly didn't want to start. Got it started somewhat but it won't iddle. I replaced the MAP sensor, the throttle position and the air management valve and still it won't iddle. When I remove the vacum hose from the MAP sensor it iddles very rough and when I put it in drive it looses power. Any good ideas anyone?
