the idle control valve won't be causing the missfire though.on mine the fuel pump relay was at the end of the loom in the engine bay tucked behind the battery.

cant remember lol. the icv is not active when the throttle is open.all it does is alow a certain amount of air through to keep the engine idling.

sorry got mixed up

throttle posish sensor right? didnt think they were adjustable on XE's?


also we've found a random black box maybe 1"x1" floating around at the back-right of the block that should be bolted down but isn't.

ideas of what it is?
