gasoline

#1

My1998 chevy cavalier 2.2L cuts out when smash the gas. We tested it and the air fuel mixture goes from 14.6 to 12.2 when you hit the gas. Starts great, idle ruffs when under a load when at a stop light. Has a new fuel filter no change, platium plus are 10,000 miles old, car has 78,000 miles. No codes at all.

clean the throttle body and mass airflow sensor and check for any vacuum leaks.

I have a 99 with 130,000 miles, sounds like we have the same thing going on…email me at coloradonative80501@comcast.net if you figure yours out. I am baffled as are my mechanics. Had alot of really good things to check out in here from 2 guys, check my posts: Help! Somebody respond please??? 99 Cavalier bogging down…
