Hi are there any servicable items in the throttle body im trying to crack an intrrmitent problem
and all looks ok externally idle switch opening and butterfly appears to be ok.
There are 2 microswitches under the squareish cover on the end. You could check these are operating OK with a multimeter. They tell the ECU throttle positions for wide open throttle and idle. Other than that I don't think there is anything in there that can go wrong.
I've not heard of any throttlebody parts going wrong although they can sometime need a good clean out.
