2003 Grand Prix GTP running like crap. The OBD2 Code is P0336. I replaced the crankshaft sensor, to no avail. The RPM's fluctuate significantly & there is a lot of hesitation, it doesn't idle well and will occasionally stall.

my '98 gtp is scanning the exact same code... stalls when temp guage gets above the 1/4 hot level (i wait a few minutes and it will start/drive again, however, if you don't. wait long enough, it backfires and won't start).. i also lose my tach and my tcs light comes on (i presume i lose my traction control)...
i bought a new crankshaft positioning sensor in hopes that that might be it.
i haven't changed it out yet.
any updates as to what your trouble was and how you fixed it?
thanks.
