i have a problem and need advise,
i recently changed the head gasket on mine and when i put it back together
it really struggles to start and when it does it stuggles even more to rev,
i checked everything but its got me stumped,
ant sugestions?
and i fogot tp mention it idols ok when it eventually starts

Did you time it up correctly?

Maybe a coincidence but maybe the TPS has packed up? I recently experianced similar symptoms to a 318is I look after for someone. Idled fine, but wouldnt rev. TPS has a potentiometer inside for throttle position, that failed. Have you got the fuel pipes on the right way round?

does sound like a faulty TPS, or possibly the dizzy.

i timed it up and checked it bout 6 times, wheres the TPS and how do you check it.
and the fuel pipes aron the right way, i checked.
its starting to get me down now, next stop scrappy if i cant sort it.

dizzy on an IS? behave! still worth checking the exhaust cam sprocket is on correctly as the cam sensor comes off this. Cam timing definitely bang on?

everything as it should be

sounds like the timing could be retarded on inlet cam

what ever it is i've had enough and thinking along the lines of a 6 pot now

m50 m50 m50 m50 m50 m50 m50 m50...

it's over rated..

Na just m20 2.5 if i can find one.
just a thought but are the cam lobes a different size on inlet/outlet

the inlet and exhaust cams are different, yup.

they are also labeled on the cams.. A and E I think E is inlet and A is exhaust..

How stupid do i feel, the cams was in the wrong way
put it all back together and its all ok now

what a relief,,,,,rodney you plonka! but i bet your well happy now
