Durring this cold snap, my accelerator is sticking but only when first going on the power, i.e after coming off the power and then back on.
I had the same problem last year durring a cold spell but it clears when the weather is'nt freezing.

I've had a look at it and i have narrowed it down the the throttle body as i can feel the resistance, though it only sticks when the engine is running.
Thats made me think its caused by something to do with the air flow/air temp when its freezing out.

I have tried cleaning the current throttle body with no joy.

Anybody have any advice on this before i order a new throttle body ?

Also is this the correct parts number for a st170 throttle body - 1143343.

Cheers in advance
