XR6 Turbo Misfire Under Load

[brock.uee]

Hey guys just seeing if anyone has any ideas about what I should check next.

 

my car has a pretty bad misfire under load (basically as soon as I hit boost it misfires and carries on). 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

if you've replaced spark plugs and genuine coils and the problem re-started again not long after, I'd say you've got a coil-driver issue in your PCM.

Gap the plugs down to 0.7mm and if they're already at that, go down to 0.5mm.

I’ll try and see what gapping the plugs does for me, and also going to pull intercooler piping off again to check there’s no oil leftover in there, and checking fuel filter, cheers
