Engine Mechanical problem
2000 Chevy Astro 6 cyl Two Wheel Drive Automatic 196322 miles
my 2000 chevy astro has serious hesitation problems when accelerating. I'ts had a full tune-up with no improvemt. The scanner shows misfire on cylinder #4 @ idle and misfire on all cylinders @ load. I've replaced the coil, fuel pump, spider web injector system and have had a compression test with the results of 180 lbs. Of pressure per cylinder, the MAF sensor is working fine. What am I missing? HELP PLEASE. Thanks, Terri
have the same problem?
