Recently I have been having problems when stopping for a peroid of 30s to 1min, the engine revs high for a moment then the check engine light comes on. It may stay on for 5min-10min then turns off, during this time the engine runs rough at idle or at speed. Checking the engine code only turns up 1222 (Lambda Control) which has been in the ECU for the last 1-1/2 yrs, I suspect the MAF is going bad but the check engine light always shuts off before I can check the code when this issue presents itself. Any suggestions?
Thank you,
Chad
