e85 2.0i misfire

Post by Eddy Matthews » 07 Sep 2017, 10:19

Hi guys,

My 2.0i Z4 seems to have a slight misfire - It is most noticeable on tickover when the engine seems to miss and "hunt" slightly. It's not really noticeable when driving, other than the car doesn't seem to like low revs - But since I'm new to my Z4 maybe that's normal? It only really pulls away cleanly at 1600rpm or higher. below that it's just flat, and no real power. The car has only done 41000 miles.

Haven't had any codes read, just wondered if you guys could point me in the right direction?

First port of call would be air leak, then on to plugs etc, but get codes read.

As above, could be all sorts from one dodgy plug, coil pack etc etc.

c£40 for a code read is better 'value' than substituting parts sequentially. The 2.0 I drove pulled OK across the range so no flat spots expected.
