Is the Check Engine light on in the dash?
nope there is no engine check light on and I was
told that mine did not have an idle speed control valve??? but Iam not sure
The engine hunts and it is more obvious from the exhaust on idle is phuts but its quite random....
car drives but seems under powered...
thanks for you help...
Look from under the car to the bottom of the inlet manifold. There will be a little silver / chrome valve assembly held on with 2 x 10mm bolts and a 2-wire plug going to it. That is the idle-valve.
It will be a bitch to change also normally.
May not be the idle valve. Was only a hypothetical cause (although it is common as muck and most dealers keep it in stock @ approx. £66)
