Splutter splutter bang bang REX
 

My car has been running pretty rough when cold. Its got a Motec M800 with breathing and fuel mods. It started pretty mild where it would splutter and cough a bit on cold mornings if i went over 3000 RPM or so. It recently had its 100,000K service which i was hoping would improve the situations but that made things worse. Now it has no power and splutters and coughs like mad for anything over 2000 RPM and it does it for much longer, even for a bit after its up to running temp. Does it at first on the way home from work in the afternoon too

Once the car has warmed up and has been driven for a while it seems to run perfect though.

Any ideas ??

Cheers!

incorrectly gapped spark plugs? Coils? Ignition system earthing?

coils

More than likely the tune.

Good ol MoTeC cold start possibly. Just being more badly behaved on these cold mornings maybe.

tune for sure

Hmm will have to take it to someone i guess.... I've seen the list of tuning shops that do Motec, is there anyone who stands out for Motec excellence? Haven't been too impressed with my regular service shop of late.

Cheers for the feedback!
