Stalling And Dying

[crusingtp]

Car starts up fine. When i put it into drive it and put my foot on the pedal it dies. I put it into neutral at stops and rev it up to 1500 rpms and throw it into drive and it doesnt die. i cleaned the throttle body and that didnt seem to help. My car died every time i was at a stop and tried to drive. any thoughts of what i should be looking at? Help is greatly appreciated.

It possible that your cps sensor is bad.

cps = crank position sensor

i didnt get a check engine light though. The car dying at a stop is sporadic. It'll happen one day and than the next it wont die at all.

the cps wont throw a code

[crusingtp]

why not? how am i suppose to know if its bad or not?

[Fivefingerdeathpunch]

im not sure why gm made it that way

[crusingtp]

im pretty sure if it was bad it would throw a code. I dont have a DIC, but i dont think thats where the check engine light is.

From the ignition control module, the PCM uses this signal to calculate engine RPM and crankshaft position at engine speeds above 1200 RPM. The PCM also uses the pulses on this circuit to initiate injector pulses. If the PCM receives no pulses on this circuit, DTC P1374 will set

unplug the Maf and see if it runs better

ill give that a shot and respond tomorrow.

would running a scan help? when im in drive and stopped the whole car shakes very badly. i dont know if that give it you any hint.

SES codes will result from emission control system failures typically. You can have a litany of other problems and not throw codes (TPS is one failure that won't throw a code).

You should see the SES light in your dash and not DIC. You should see it light during start up. If not, you won't pass an emissions test (at least you couldn't here).

cleaned the maf sensor. One piece looked a bit oxidized. I checked for resistance and got 20 m. what should i check next?
