Hey all.
I've been having some issues with the throttle of my Astra 1.9 SRi. It's a 2005 model with the turbo diesel. I have a few different ideas of what the issue might be but I want some input from you folks too.
Basically, you can start the car up in neutral, tap the throttle and nothing happens, car doesn't rev. But if left idle the revs slowly climb on their own. The car is applying the accelerator itself. (This is replicated while driving and especially dangerous when the turbo catches on to the power).
The car throws up no faults on OBD2 and flashes no lights on the dash. This makes me think it's a mechanical fault, possibly a sticky valve in the throttle body, though I may be wrong.
Any suggestions?
TIA.
Dylan
