tc- traction control, the tc unit sits between the throttle body and inlet manifold

My TC light is on, (to dear to fix

), but it still revs through range

to be fair my TC has never worked either, had the butterfly removed and took the bulb out the dash. problem solved

Nice one,but i did something little more tech.

I cut out a warning light size piece of black insu tape and stuck over it !

OK - I've fiddled with the TC motor. With the engine off the connecting lever can be moved smoothly though its travel. With the engine ticking over it moves through about 5 degrees and then I can feel it coming up against the tip of a rotating cam or similar inside the motor stopping further movement - the lever vibrates as the motor rotates. Any help?
While I'm in TC territory, I had assumed that the traction control was switched on by means of the button near the base of the gear lever. Research into the manuals I have suggests that I have that the wrong way round, and that TC is ON when the car is started. The TC light comes on if I then press the button. It does not flicker at any point to suggest a fault.

TC is on all the time, you do need to press the button to switch it off.

It has been suggested to me that it could be the fuel pump. That fits most of the symptoms - like the limiting when I try to accelerate - and the temperature bit may just be that the hot day pushed a poorly pump over the brink. I'll do some checking up.

I have replaced the fuel pump and filter. No difference. I now have a spare (if used) in-tank pump and filter. The next thing I shall attack is the throttle potentiometer. Watch this space!

That would depend on who you are. :whistle:

Throttle pot made no difference - if anything it's worse. Just aout ticks over once its warmed up a bit but any amount of throttle causes it to misfire. Can't even pull away in it now!

You could try changing the coolant temperature sensor as the problem seems to come about when your car is warmed up. They only cost about £12.
Make sure you don't buy the temperature sensor for the gauge in the car which has a single connector on it
