Engine racing at junctions?

Hi, just wondered, as I had thought nothing of it until a passenger recently said it didn't sound right!

 

At junctions where I have to wait for the lights to change, etc, before moving off again, it seems that my engine is racing or over-revving sometimes. It's usually changed down to first gear (1.6 auto) by the time I stop, but still racing.

 

If I put it into neutral the revving stops, or if I just lift my foot off the brake and then immediately apply it again, I get a little jump, then the engine drops/stops revving and doesn't race any more. This doesn't happen every time I stop, but does more often than not. On the times the engine isn't racing, it's so quiet inside I wondered if the engine has stalled a few times until I got used to how quiet it was on tickover.

 

Anybody else know if this is ok or not?  Thanks for any replies.

There was a batch of duff throttle pedals around 2007 - my 2007 Scout has just developed the same problem. A replacement is about £105, or a squirt of PTFE if you're cheap like me :)

    I thought PTFE was a plumbing tape, but I'm just a girly!  Do you mean WD40 or something? And where to squirt it? He he he rude answers on a postcard please! :D

    I tried the pedal reset and it made no difference to my car. 

     

    I bought WD40 PTFE from Halfrauds and sprayed it sparingly between the pedal and the body of the unit on both sides ... that was a few weeks ago and all is well. 

     

    If you intend to squirt it elsewhere .... we may end up in trouble with the Mods :)

    Sorry for the confusion, I didn't know such a thing existed!  I tried the pedal reset and it hasn't made any difference to my car either... I have some electrical contact cleaner made by Silver Hour - would that do the same thing?  Says on the can 'for the effective removal of stains, coatings, oil, grease, dirt, etc..'  It would save me a trip to Halfrauds, 12-mile round trip for me.

    No, in my experience you need a PTFE 'dry' spray - contact cleaner made no difference to my car.

     

    It doesn't have to be Halfrauds, and decent motor factor should sell it

    Update: I went to my local car accessories shop and they didn't have any WD40 PTFE spray, but had some Silicone Maintenance spray, so I bought some of that and am giving it a whirl... don't know if it's done any good, all the traffic lights were on green on the way home from buying and using it! :)

    You should notice a difference in the feel of the pedal, it should feel a lot freer under foot, almost like its not there anymore.

     

    My partner's Roomster did the same. I thought it was trying to do regens (being a diesel) but you would let the clutch up and the car would take off. I gave the pedal joint a spray when I realised what was going on and what a difference it made.

     

    I just used silicone spray too.

    Thanks for that, Rich. The pedal did feel a lot freer actually, that was one thing I noticed almost immediately. Although I didn't get to see if it was still racing at stopping points.

    I don't know if it was the hot weather or not. But the racing was back when I used the car yesterday. :( I've tried using the silicone spray again, hopefully it will work next time I go out!

     

    It's beginning to look like I have one of those duff pedals. :(

    One last thing to try, best done at a standstill, try lifting the pedal back up with your foot. If it is just a sticky pedal, lifting it back up should let the engine go to idle. If it's the sensor part, this should have no effect.

    If it does idle normally with lifting the pedal, try a bit more spray while working the pedal up and down with your hand.

    Hope this helps.

    It does seem to be a sticky pedal, as I can lift it with my foot and the engine stops racing.... sometimes. Tried all the above suggestions and it doesn't work with the silicone stuff, so I'm wondering whether to go and get the proper PTFE spray and give that a whirl. Or take it to my local garage....

    Probably worth getting a pedal, they are known to be iffy.

    Agreed. The spray should work straight away. Sounds like the pedal is a bit far gone unfortunately.

    I've ordered some of the proper stuff, the PTFE spray as on the link. If that doesn't work, then I will have to get a new pedal!

     

    If I need one, where do I get a pedal from? Just might be easier for my garage chap if I got it in advance?

    Skoda, skodaparts.com or Briskoda parts.

    A few months ago I had the same problem in my 1.9 tdi  Roomster.


     


    I took it in to the dealer and I suggested it might be the accelerator/sensor that was the problem.


     


    I took it in for diagnosis and yes it did need a new accelerator and sensor.


     


    They charged me £33 to diagnose the fault and £195 for the repair. It's runs fine now.

    So you got charged £33 even though you told them what the fault was ?? Flippin' 'eck!

    That's a main dealer for you.

    I only expected to pay for the repair so I was a bit miffed to say the least.

    Of course they are going to check. What would happen if they fitted the pedal and it didn't fix the issue?
