    car stalls at light ?

    this happens to me every once an while. ill be sitting at the light and the engine just shuts off without warning, and the red oil light symbol comes on near the tachonmeter. i also get this DIC message "check oil level" i have and it is full. any ideas to why my car is stalls for no reason when stopped?

    Have you checked for any engine codes? It could be a number of things, but on my STS the crankshaft position sensors were going bad.

    yeah, when i start the car sometimes it takes awhile to ignite. wonder if it has to do with the crankshaft? my only two codes are PC1139 and AC1347, most of the time the PC1139 is in the history but sometimes it kicks in to current and says service emissions.

    Are you sure you wrote the codes down right? The first one should read P1139, and I'm not sure what the other one is.
    But the P1139 is for a oxygen sensor problem.
