Throttle position sensor? or even bad coil pack?
Thanks just checked coil pack it good...and any way to test the sensor to see if bad....Thanks have been combing internet for help am glad found this page
Usually by unplugging it when the car is on and it the car doesn't react it's usually a good sign its bad, its usually located some where near your throttle body on GM cars.
Do you know if your fuel injectors are firing and when it cranks is it really fast slow or normal
