Title: Stutter/missfire/hesitation between 3-4krpm
Post by: rhydV6 on 16 October 2006, 19:07:07

Does this in every gear, not that harshly but if I plant it, it will accelerate well up to 3k then slight pause then power on again strongly, if that makes sense?

Any ideas?

Was an intermittent thing but now it does it in every gear under all road conditions :(

Car is '98 x25xe cheers

Assuming no EML, I'd check for oil in plug wells, ht leads, or DIS...

I'm not sure power would come back at 4k if it was DIS or leads. Doesn't something happen with the multiram between those revs and couldn't that cause this problem? My memory isn't very good these days but I think I hear a distant bell tinckling  :)

Yep, i was thinking more multiram than DIS.

I'm sure MarksDTM will have the deciding vote.  ;)

Does sound like multiram. Or possible crank sensor - remember that limits to 4k, so could be intermittent or just FUBAR'd.

Cam sensor limits it, crank sensor stops it...

Rereading the original post, I would be inclined to check multiram operation...

Any fault codes?

Front multiram is the favourite.....

Had a very similar thing happen to me not so long ago. It turned out to be one of the vacuum pipes had come off the front multiram. Once it was reconnected the problem was solved.

No all hoses are connected..

So what exactly am I looking for then?

'Sounds like multiram' doesnt help much tbh, does this mean multiram needs replacing or fixing? etc...
