hi brickboard,

still got a problem with volvo 940 2.0 turbo.
Rough running when running up to 2000 rpm and a bit ropey after that.
Swapped out coil, leads, FPR, cleaned distributor cap up. All spark plugs a nice pale consistent colour, cleaned out IAC controller (checked it snapped open OK with a 12V battery - fine).

Dont think its rpm sensor as that would probably be a no-start type situation, tried a dodgy one I had and it didnt make a difference.

I've got no reading on my temp gauge on the dash which didnt strike me as unusual as the fuel gauge packed up long ago, but it's led me to wonder if it could be a shot engine temp sensor. Would this produce the intemittent rough running? Sometimes (rarely) it seems to run OK thought the gauge is always not working.

The only other candidate I suppose could be radio suppression relay, does anyone know if on a UK car its jammed down behind the turbo air cleaner box? and is it accessible.

any ideas welcome
