09 Tsi Gti, 118k. Car starts up and runs fine for a while, but like clockwork when nearing 40 minutes of driving and coming to a stop or fully stopped, I get a flashing CEL. RPMs drop a bit then go back up as well, Obdeleven shows misfire all cylinders and always misfire on cylinder 1&4.
Its weird, as long as my commute is under 40 minutes, I get no misfiring at all. Car runs great under any kind of throttle. Replaced spark plugs and pcv. I do plan on replacing coils and have a valve cleaning done.
Any help, or insight is appreciated.
