Heavy accelerator and lazy speedo...

[nia198]

Acccelerator - Was fine on my way to work this AM, but when I went for lunch the pedal was much heavier - have to press it further to get to any power and when it comes, it comes with less travel than normal.

Speedo - Flips between normal operation and reporting 0mph (quite worrying when in speed camera terratory, as dispite trying to remember, I keep forgetting what rev numbers mean what speed!). Will drop to zero for anything from a few secs to several 10s of minutes at a time. Seems to go back to normal if I change gear sometimes, but not always. Was looked at in my service 2 weeks ago and they checked the gap in the sensor and thought they'd fixed it, but it appears not..

Aany ideas?

TIA.. Nick

Your throttle cable is fraying and about to snap, and your speedo sensor is either faulty, or has a wiring fault, or not positioned correctly. I don't think the two problems are related. Obviously the throttle cable is liable to leave you stranded unless you fix it.

I thought the ECU had a speed sensor signal going to it, uses same sensor on diff then two feeds one to speedo and one to ecu. I'm not sure what the ecu uses this for but whats the odds of this and the cable going faulty at the same time. Is there some idle control vs speed control and the ecu thinks the cars stopped when your pushing the throttle.

Thanks Peter - will give teh garage a call and get them to check it.

Chris - I'm pretty sure the two things aren't linked. They are both not right, but the speedo has been like this for about 3 weeks now. The pedal issue started yesterday.
