I have a 4.5 cerby and when I come off the throttle the revs are sticking for a few 10ths of a second, the car wanting to go whe I don't (a little hairy at times). The local dealer replaced the throttle cable and is suggesting other stuff, anyone have an idea (or experience) of the what's happening.
When I looked back in the history of my 4.2 I found it was going through a throttle cable every 9-10k miles so it was rubbing on something to wear through the strands of cable. Maybe on yours, despite having the cable replaced it could be getting stuck in a groove it has already worn. Increasing the strength of the return spring may stop it getting stuck but it wouldn't stop wear. It could still be some other problem. If you operate the throttle linkage at the back of the engine does everything move smoothly there. Is something potentially obstructing the return or maybe the pivot bushes on the controls are sticking. I'm only guessing but I imagine it is a quite simple thing.
When the dealer fitted the new cable they fitted a stronger spring with no difference, they have advised me they think the next step is to strip the throttles down and take the spindle off the car to clean everything up which is pretty labour intensive. I am not that competent mechanicly and prety much rely on a mechanic knowing his stuff/ I can trust, but I am just a little concerned that I may pay for work that does not fix the problem, do you think this proposed work seems like the next sensible course of action
