misfire when cold

[stuartyhall]

In need of a bit of help/ advice.

Over the last couple of weeks the car has started running lumpy and sounds like its misfirng when its cold. It struggles when its left to idle when first started up from cold. If you try and drive it. it refuses to rev past 2k where it sounds like its misiring when it gets upto 2k. after a couple of mins struggling to rev etc. it is like it kick and clears. then runs fine after. Any help would be appreciated.

Most likely either an HO2 or CTS fault. Ideally a look at the live data whennits properly cold will confirm or deny this.
