just had a the motor out and a couple of days after it was back in just cruising at 35 mph the engine cut out had on and off several times, while it cut the Check engine light came on but when it cut back in it went off. Drove home and it was fine. today i was driving it again ad it starting doing it again cutting on and off repeatedly and finally cut off altogether. i was able to limp the car to the side of the road and let it idle for about 5 minutes. drove it to the dealer and it drove fine and dropped it off. They are going to drive the car and do some data logging. but my luck they wont be able to reproduce the symptom because it doesnt happen all the time. anybody got any suggestions? thank you.

Any kind of noises? CELs coming on? Do you have a Cobb AP or anything to check codes? It almost sounds like an injector/pump issue of some kind. Perhaps a pressure problem...just off the top of my head. I've had injector/pump issues that's why I say that.

No noises and the CEL only comes on during the cutout part. It's very jerky, I don't have an AP but the dealership is datalogging it.

Crank sensor (faulty), MAF sensor (dirty/faulty), timing belt (loose or going bad)...or one of the aforementioned fuel parts is my guess. Anyone else have any input?

Just because the CEL turned off doesn't mean it is not still in memory. Get the DTC .

We hooked it up to the code scanner but there was nothing in the memory. The dealership is datalogging it right now and hopefully it's something simple. When they originally gave my car back to me after the head gasket replacement the technition forgot to plug back in the knock sensor!

What tune are you running to support those mods?

 

[deepseastetson]

It was tuned by randy at national speed inc. never had any problem like this before. The motor was pulled out by the dealer to replace gaskets and seals. When I got the car back it started cutting off and on while driving normal. I brought it right back I the dealership and the said they were going to check it all out seeing how this problem did not occur until they worked on it. They were Suposed to get back with me today but they didn't.

Ok the dealer just called me and said they think it's either the ECU or the ignition switch relay. If its the ECU than I am going to have to get my car re-tuned. The technition is on the technition hotline because he probably doesnt know his ass from a hole in the ground.
