Wont idle runs rough


Can you hear the fuel pump running when you turn the key on-if you can is the fuel making it to the fuel rail injectors. It sounds like you have a bad fuel pump. check the fuel pressure with a gauge at the fuel rail-there should be something that looks like a tire inflator valve stem that you connect a gauge to. you may also have blockage-a bad fuel filter-Hope this helps Denny

Unfortunately, you might have to replace every sensor until the problem goes away. It is a matter of process by elimination. I am in the same position. Good luck

Change the PCP valve and run the heater. This should take care of it. You only have to run the heater one time as this is controlled by the vacuum system. This will cause your motor to run proper.

i have the same exact problem, i have replaced fuel injectors, idle position sensor, idle air sensor, map sensor, temperature sensor,. the only way i can make mine run ok. not great is unpluging the map electrical connector, and it still has no power if u gas on it but it makes it down the road and smells rich, if u find out let me know what the problem was i really love my truck and hate that it doesnt run right, Redemmett21@aol.com

Check your MAP and TP sensors. Your throttle body may be having trouble determining position and is compensating by adjusting RPMs.

Car wont idle


you may have a vacuum leak, check all the vacuum lines around your inlet manifold, carbi etc for cracks or ones that have come off their fitting.
Check all the retaining bolts and nuts around the manifold, they may be a bit loose.
