Car is sounding lumpy as if a plug has gone .. Losing power then returning to normal except on higher revs.
blew black but has now stopped .. Still idling lumpy,power is up and down.
Help!

It sounds like only part of the idle is rough.
Cheers I will!

u fix a vac leak by either cutting hose shorter
or replacing it completely

Another thought is I caught on something slightly backing out the other day, could it have pulled the intercooler forward a bit and loosened the air intake.
Would that be the response if that happened though?

I went to check the plugs, 2 of the nuts for those covers screwed over the top of them are burred so I'm getting the mechanic to do that, but I'm thinking of other cases just in case.
Plus it helps me learn more about it.

Nah inter cooler and pipes from it are fine, I'll give a quick look over the hoses for safe measure I guess

Hoses are all good,
It wouldn't start though, oil light came on sometimes during the attempts ..
Could it be a starter motor or something giving out or ignition unit?

It's been running rough for a few seconds then idling perfect on start up since I've bought it.
I'm wondering too if it could be something to do with it

To catch you up on what's happening, its been diagnosed that it's an inconsistent current.
Whether it's the comp. Or just a connection gone bad I won't know til mid next week as she's locked away for the long weekend.
