I'm going nuts trying to find this problem. Dies or cuts out when cold. Idle goes down and dies at stop lights when hot. Tried 2 new IACs, new O2 sensors, new plugs, new COPS, new injectors, new fuel filter, different battery, different alternator, etc, etc, $$$, $$$!!! I don't want to pay for a MAF and find out it is not the problem. Someone out there has a stock MAF for cheap. Let me know. Thanks

first off....before you spent all that wasted money on things your car didn't need you should have just had a good mechanic take a peek at it. probably would have saved you alot of money. now a maf could cause your problem. take it off and clean it with either elec. cleaner or maf cleaner. report back with results if that doesn't fix it then we'll go from there.

Maf has been cleaned. Checked EGR valve and it's fine. NO CODES. What would cause this and not give a code?
