I’ve got brand new spark plugs and genuine coils. Intercooler has been cleaned so there shouldn’t be any oil residue in there from my old turbo sh*tting itself. The car is 480kw on e85 so it’s very noticeable when you hit boost and it misfires. When I replaced spark plugs and coils it fixed the issue for about 50km then it came back, I’m thinking of checking spark plug gap next? Just seeing if anyone has had the same issue. ive read other threads with this problem but nothing really helped Link to comment Share on other sites More sharing options...
