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
