Throttle sticking on but not when TC is off

Anyone encountered this problem before and know what it might be?

Cheers, Carl

Traction control working as it should...

Perfectly normal

Stop driving like a tw at, and the ecu won't keep cutting the fuel

I read this that throttle is sticking on, I.e. High revs, but not with TC on... Total opposite to the above comment 

[05omegav6]

My bad... appears I completely misread that

But given the throttle is electronic and TC cuts the fuelling (as well as triggering the rear ABS) I don't see how turning the TC OFF would prevent the throttle sticking open, as throttle control would remain the same... the difference being that with TC disabled, it would have no fuelling over ride to the ecu.

If it is indeed sticking open TC off, then I would be looking closely at the ABS to Engine ecu wiring.

When I get into it each morning to go to work if I where to rev it up to say 3-4k then change gear it would stay at them same revs and so on but I've notice that if I turn the traction off It doesn't do it at all its like as if crusie control is stuck on because the revs always stay the Same, they never go up or down.

Very strange it's only started doing this it was driving perfectly okay

Does it have cruise control?

[C20det]

It doesn't need to be high revs for example I'm driving along the carriageway at a steady pace with the traction control OFF at around 50mph @ 3000rpm  and I turn the TC back on I would be able to lift my foot off the throttle pedal & it would continue to travel at that same speed until I either press the brake pedal or turn off TC again,

Yes it does but the fella I brought it from told me that he had took the stalk out of it because something was interfering the with it but I can't remember how, there is a non cruise control standard stalk on it from I bought it .

[C20det]

I think he mentioned something about the clutch pedal interfering with the cruise control that's why he changed the stalk, as far as I can remember

If clutch switch still present, try unplugging it and see if it makes any difference?

[C20det]

Okay will have a look in the morning, 

Thanks

Would it be churlish to ask what codes are present, if any...

[Andy H]

It would make sense if switching TC off also disabled cruise control. The fact that someone has previously removed the cruise stalk makes me suspect that there is a short circuit (perhaps intermittent) in the wires to the cruise switches which is setting cruise when it is not wanted

Being Plod, if cruise is fitted, then it is unlikely to be factory... Needs activating with Tech2 to work properly, and if "My Naff Code Reader" has been used on it then all bets are off...

They wont let you enable cruise on the 3.2
