Hey how are you? Found this thread when doing searched on these forums because of my problem. I had a shop install EL catless headers, and I did a stage 2+ OFT tune when I got home, car has even driving for a week just fine. Today as I was doing a J turn in the cul de sac on my block the car stalled and I cannot get it to turn back on now. Not sure what the problem is. Do you have any ideas? Thanks.

Isn't there any error code or CEL? I had such stalls for two different reasons both came with different trouble codes.
P0172: engine was stalling at idle after warm up. It was MAF sensor and MAF extension cable replacement that fixed it.
P0301: cylinder was misfiring at idle. You can feel the engine hopping in this case. It was valve springs replacement that fixed it. But it could have been spark plugs, ignition coils, or injectors as well. Hope this helps

Thanks, I have no CEL light on so I don’t have a clue what the code could be
