Ok, I've tried it all,.... First I replaced the CKP's since it only stalls coasting to a stop or stopped. I have read multiple old threads and tried all things that I didn't think would cause it, and I'm still having the problem. To be more specific, it stalls with the engine hot or cold and only when coasting to a stop or stopped. It will do it 2 to 3 times a day in heavy traffic. I just replaced the head gaskets on this car and all is great except for this. The ONLY code is P1599 (engine near stall or stall) which makes this even harder since I don't have anything else to go on. Here's what I have tried,.... different EGR, different TPS, different cam position sensor, different IAC,...... I think that's all.. I've read about possible FPR, but I don't think so since it starts right up and never surges,...... I am going to try another set of coils, but once again, it never misses during cruising or acceleration. The backfire valve????? Never seen a bad one, but I guess I may try that as well. It definately doesn't have any vaccuum leaks either since it idles perfect when it doesn't stall. I didn't do a relearn on the ckps since everyone said it wasn't necessary, but should I give that a try??
