Poor Idle Part 2
95 LT1 A4. I am going nuts with a slight stumble at ldle. I have jumped the diagnostic connector and the system runs to a "1.0". Can't find this code anywhere. Am not sure if that is a code or if the system should go back to C12.
Have replaced the following:
TPS, IAC, fuel filter, fuel pump since this problem started a couple of weeks ago.
Replaced the Optispark, wires, plugs water pump and timing cover seals about 6 months ago.
Have checked the wires and grounding.
Car still has slight stumble while idling.
