I'm at my wits end with my Astra 5 door Hatch 1.8L Mk4 with Automatic Transmission.
Essentially the car drives quite well (although on occasion it labours like it is in the wrong gear for a few seconds). The major problem is a rough/harsh idle, particularly when under load such as when drive is engaged. Lately I've been getting the fault code P1555 more and more often.
Today swapped out the throttle body for a new one and it made absolutely no difference. I thought P1555 related to the throttle body...
I unplugged the MAF Sensor to see how the car runs with it unplugged. Strangely it runs exactly the same if the MAF is plugged in or not. Does this means the MAF is okay or stuffed?
Could it be a gear box issue?
Could it be a peddle speed sensor issue?
Vacuum leak?
Something else?
I'm growing to hate my car, any assistance would be appreciated.
