mojoex Posted March 26, 2014 Share Posted March 26, 2014 Hello All, I'm a new member with a very well looked after 5 door ST170. It's an 04 plate so (I think) it's one of the later models. I purchased the car at the beginning of January after having a terrible time owning a Citroen C2 Code (Don't ask..) and I was initially looking at a Fiesta ST150 - but I do a fair amount of motorway miles so I opted for the 6 speed ST170. The car is in fantastic condition and has flown through it's service and MOT. It's done JUST over 69k. Very recently I had an issue with the water pump bearing which has been replaced - however since I purchased the car some odd things happen with the accelerator. For a start - it is initially hard to press in, almost like it is sticking at it's most extended point. This requires a little force to unstick the pedal, which results in a sudden jolt once the peddle is free. Additionally, I get a large amount of pedal vibration above 3.8k revs. It sort of fades away if the revs continue to climb, but it's definitely still there and it's very uncomfortable - especially if driving on the motorway. I have people telling me that it could be the butterfly valve being clogged up, or the throttle cable needs replacing. I took it to a Ford garage and they 'acknowledged' that there's a problem but they have booked me in on the 31st for some more 'investigation'. So I'm no doubt going to be spending a lot of money on this. So my question is, have any of you had this problem before? I have checked the common issues and performed a quick search but I haven't had any luck thus far. Any help would be much appreciated as I have rapidly fallen in love with the car!

Luke23 tdci Posted March 26, 2014 Share Posted March 26, 2014 Ye you are on the right lines with throttle body. Take it apart and give it a bit of a clean. Gets a bit grubby inside. Quote Link to comment Share on other sites More sharing options...
mojoex Posted March 27, 2014 Author Share Posted March 27, 2014 Thanks for the reply mate. I'm not a mechanic but I'm not afraid to give things a go providing there's no risk of me breaking something important. I'll give that a go later today. I would've thought that it would be clean though as it's recently had a lot of work done to the engine, and it looks clean throughout.

Gazst170 Posted April 4, 2014 Share Posted April 4, 2014 Hiya I was wondering if you managed to sort you vibration on your accelerater pedal if so how did you solve the problem. Ive got a slight vibration doing 70 or above. Only slight but would like to sort it out.
