91 z28 idling erratically
My 91 z28 is idling erratically in gear new fuel pump Delphi and south Bay injectors along with new cts sensor O2 sensor tps and iac plus EGR valve and ecm I disconnected the coolant temp sender and it's better but not perfect any ideas I know the sender doesn't communicate with the ecm but why would it run better disconnected? Car is stuck in open loop too
