OK story so far, The car was hard to start from cold - other posts from the group said it was the coolant sender or a fault with the Idle stepper motor - so I took both off and cleaned (or banged lol) Now the car started great last night - now its revving to the roof!!! any ideas? or is it time for a new stepper motor? Thanks in advance Martin |

air idle valve might be stuck open. drive the car for a bit and see if it settles down, if not you could try resetting the ECU, thus forcing it to re-learn everything.. its possible that the adpative learning has got used to a sticking valve, and now its not is over compensating...

Assuming the connection was dodgy for the CTS and after cleaning it you have fixed it. The high idle, assuming you have re-assembled the stepper motor correctly and the linkage isnt stuck for some reason (dont like mention of hammers, these things are not to be bashed about) then you most likely have a new fault with the microswitch on the tip of the stepper motor rod. This indicates to the ecu when the throttle has shut (by the linkage pressing on it) so it will then drive the s/motor to control idle speed. I assume the ECU is driving the stepper motor back and forth when you cylce the igntion? If not, then the motor isnt getting power at all or is dead, and is stuck in its fully extended position giving a racing idle... Tim.. --- Outgoing mail is certified Virus Free.

Thanks in advance Martin Time to say good bye to the 106 dealer wants £525 Inc VAT for part - not going to risk 2nd hand parts I don't think. The wee b*tch has been a money sucker the past few yrs - never again will I buy new! Martin |
