I just purchased this truck and have put new plugs and wires, new iac, new coolant temperature sensor, new 02 , cleaned throttle body,. I am having issues with a jumpy idle especially in park or after sitting at a stop for a moment, no codes and it doesn't die, it did get better after iac and coolant temperature sensor. any ideas of what else could cause this?
No announcement yet.
