Alfaowner you saved me! Throttle reset...
I broke down yesterday in the Asda Car Park at Monks Cross shopping centre in York.
Injector light came on, then the car would only rev to 1.5k revs and no more. Then the car refused to start and the engine key code light came on. This was after some heavy rain which I suspect got into an electrical connection somewhere....
Anyway, the RAC were about to tow me to a garage when I looked up on alfaowner forum on my phone for gtv throttle problems. Someone posted about doing a throttle reset. I tried this thinking it might just work and low and behold, it did! I could not believe it.
This is what I did just for anyone who experiences throttle problems...
1 - Turn ignition to MAR and wait for 90 seconds.
2 - Turn ignition to STOP and wait for 90 seconds (and DO NOT TAKE THE KEY OUT).
3 - Start engine WITHOUT PRESSING YOUR FOOT ON THE THROTTLE.
4 - Leave car idling AND KEEP YOUR FOOT AWAY FROM THE THROTTLE!!
5 - After 2 minutes the injector light went away on the dash and I was able to rev the car as normal and drive off. (Some say to leave the car longer than this).
Thanks to the knowledge on this forum, I probably saved myself a massive bill, so thanks everyone!
