Geoff Brooker Posted May 19, 2019 Report Share Posted May 19, 2019 Hi all, driving back from TR6 day today at Wroxall ( fantastic day - thanks to all involved ) and car suddenly surges up to a range of 3000 to 4000 revs and will not return to normal -luckily I was only 5 miles from home but the car basically drove itself home and I did not have to touch the accelerator! I was busy braking and switching between 2nd and 3rd just to try control it ! when I got home I cut the ignition and then re-started - the engine immediately went to 3000 rpm in neutral. i have no idea what could cause this but can only say I did make rare use of my overdrive today as if was a long motorway journey - could that be the problem ? any help greatly appreciated thanks Geoff Quote Link to post Share on other sites
BlueTR3A-5EKT Posted May 19, 2019 Report Share Posted May 19, 2019 Sounds like it could be.... Throttle cable outer casing may have come out of its socket, holding the inner cable tight. Wobble and fiddle with the outer throttle cable where it ends. It may just drop back to its position Cheers Peter W Quote Link to post Share on other sites

Aldpilot Posted May 19, 2019 Report Share Posted May 19, 2019 I occasionally have a similar issue when the throttle stop gets caught under my rubber over mat. Frightened the @#£& out of me the first time it happened. I now make sure the mat is pushed well into the footwell, but it has caught up once more when the mat moves.

John McCormack Posted May 20, 2019 Report Share Posted May 20, 2019 The outer casing of the fast idle (throttle) cable on the choke might be stuck on the lip of the bit it goes into at the throttle body. Quote Link to post Share on other sites

I had that happen in the car park of a "World Peace Cafe" in N Yorks. Certainly disturbed the peace when I blipped the throttle and plenty of popping and banging when the rev limiter kicked in!
