Ok, i have a 95 Lumina 3.1... IF you can actually get the car to start it stalls rite back out....Or, itll stay running till you touch the gas pedal... But if you play with the throttle you get it to stay running for awhile... but once you let it go back to idle itll either stall are start chokeing out real bad.... also while giveing it gas, if it dont just stall out it will hesitate real bad or eaven have a drastic drop of RPMs.... I replaced the coil packs lastnight ( it was aound -3 lastnight...burrr) and that didnt help....im sure this is just a continuation of the problems its ben haveing for a couple months, i cant figure it out, my mechanic brother cant figure it out, and owner of JBR Automotive cant figure it out... Today is the first time it ever threw the check engine light though.... So maybe someone can tell me which two turminals to jump under the dash to do a diagnostic test... ive got the paper clip i just done know which two terminals / pins to jump. any help would be awsome.
