well ive sussed it, the car was reving by its self up to 4,000 but only happened when it came to temp then would not start until it had cooled down, so the fix was a coolent temp sensor, in doing which i snapped the termostat housing off at the block trying to shock the top cap bolts free. so its been a mad dash to get a new housing and thermostat ect.. fitted it all thursday night and BAM fixxed.
i thought i would follow this up because when you search these things you get a lot of drivvle and when they finally fix it they dont bother posting the solution. so there it is coolent temp sender.
thanks
