Lumpy as hell!!

[Scotty-boi]

Just been out to the car to get the bin out the garage. Car is always a little lumpy when cold. But today seemed extra lumpy on idle. But not bouncing the limiter like crazy. Just normal. But the car seemed to be moving an awful lot while stationary. Any ideas peeps?

Anyone?

Sounds like a missfire, spray WD-40 in all the coil connections. If no joy, remove the inlet plenum and check for water on the plugs and spray with WD-40 again. Also check for rubbing and damage on the HT leads while doing so, if nothing's to be seen then I would replace plugs, then coil and potentially crank sensor in that order.

If you have a code reader then stick it on, will probably point you to a problem/ cylinder it may be miss firing on.

Thanks for that chap. Somewhere to start. Does feel like a bit of a misfire. Need to get it sorted. Felt dodgy as fook. Cheers fella. Just hoping its not something alot more serious
