OTHER SYMPTOMS
Check Engine Light:
Etc: No check engine light non what so ever. Misfire early in morning. Ordered o rings for upper intake manifold. only CEL i have gotten ever was a P0244. Maybe it might be a tuning issue? I dont know. I know its a touchy car right now. But she climbs hard 3-4 now that updated the cobb AP with the up to date firmware. have not checked boost levels now.
When engine has reached operating temperature, sporadic engine stall when coming to a stop sign or light. If you blip the throttle as per video, it wants to stall but rebounds. Other than cleaning the OCV, TPS, ordering new front 02, then replacing on a hunch a #4 coil, then #4 injector, im at a loss.
RESULTS
What has and hasn't worked for you:
If something worked, how long has it been working for: Ive only had the car for a week and a half / 2 weeks. Inherited someone elses troubles i guess you could say. It is what it is. it is my car now though. But Seems to be a very common problem though. I just wish it would spit out a CEL for me, then i would know what to do. Here are two videos for reference. First video is of the morning start up. It is misfiring. Orings for upper intake manifold????Maybe. Ill let you all know.
2nd video was just a little bit ago. Blipping throttle. You can hear and see it wanting to fall on its face but then quickly rebounding.
