My 98 GTV 3.0 has just started doing the same. Could it be the cold weather?
I noticed last Saturday, idle was not very stable. The needle was hunting around between 200 to 1000 rpm.
The next day I ran the car on idle from cold and it was fine, went to reverse and stalled, then kept stalling. Yesterday the car would not start unless I disconnected the switch for the air flow meter.
Does anyone know if running the car without this plugged in will do any harm, I've heard it makes little difference. I wonder if replacing the air flow meter would solve the idle problem as it all started together.
Any comments greatly appreciated.
