at different times while driving. It does seem like it does stall when letting off gas. No codes have been sent. Need help
 


or MAF sensor is bad, does your TSC light come on? does it idle rough? do the RPMs drop to 0 suddenly while driving?
 
no lights come on, no codes given as it just quits running. letting it sit from 3 minutes up to 20 minute it will restart.
 


when you put the key to ON before you crank then engine you should hear the fuel pump whine comming from the underside of the car...if you dont you may have found your problem
 
Someone told me if the tach needle moved while trying to start engine then it wasn't the crank sensor, i don't know
 
CPS can work and not work randonly so it is hard to tell, if the tach is dropping to 0 suddenly and the TSC light come on thats a sign of the CPS failing
