Just been trying to sort out a fault that has been rearing its ugly head over the last couple of days. When i start the car and put into drive the car is trying to lurch forward. Other times starts and runs o.k.
Cleaned out the oil around the plugs. Changed plugs for new Vauxhall ones. New gasket and sealed. Checked to see if the oil had made its way back around plugs but bone dry. Took off throttle body and cleaned. Also breathers and other pipes.
Started up and ticked over and responded to throttle.
When Mrs. DaveL went to go out in car engine started but revs up at 1500, no throttle response. Auto gearbox check with EML lit. Switched off and on a couple of times and fault still same.
Of course when i tried engine perfect....tried the engine after Mrs Davel left for work and fault came back. Change cam shaft sensor for known good still same. No vacuum pipes off or rubber pipe work leaking.
When the fault comes on there is no response to the throttle just steady revs, am i right in thinking it must be the throttle body or connection to it, remember mine is fly by wire.
Your thoughts would be appreciated and i am sorry for the long story.
