Missfire

[boundsw]

Alright Chaps.

Dunno if this is just coincidence, but changed my oil last night, ran engine flush through, and replaced oil filter.

Took the car out last night...fine, engine sounded smoother than ever.

This morning, on the way to work, keeps missfiring when the boost tries to go over about 0.7-0.8 bar :(

any ideas

Check all ignition components...

Dizzy

Leads

Plugs

Yeah, have got new Blitz spark plugs, with the gap set down.

and when the cars warmed up, it seams ok ?

i dunno, will prob end up getting new cap and leads

copper contact cap, and which leads so you recon ?

dizzycap and rotor arm

check for boost leak, if you just did your plugs did you undo the intercooler pipe?

else with no leak it will be cap, arm or plugs
