Title: 1222 code
Post by: 318lotis on August 16, 2012, 07:00:25 PM

i cant figure out why i'm getting the 1222 stomp test; the engine idles fine and runs fine. check engine light comes on when accelerating and then goes off when de-accelerating.. anybody ever experienced this problem?  thanx

mine was a crack in the intake bellows.  movement of the engine allows it to leak vacuum,  then close up again.

Ever figure this out? Mine is opposite....check engine at idle then goes off when I accelerate or give it gas. Good fuel pressure..no vacuum leaks...new plugs..new o2 sensor..
