What mileage you at?

Stock or tuned?

Have you read the ECU with ISTA and done any data logging?

I’m having the same issues but I changed the injectors plugs coil packs. But when boosting I still have the same result haven’t done a compression test but doesn’t misfire while idling. Any help is appreciated coded the injectors they were a (215) eu6 injectors so the correct injectors. I’m starting to think it’s a valve issue.

Although when I did a launch a couple times it would be fine it’s just under heavy load

Hi,

Has anyone found a solution for this thread?

[justbrappin998]

so it all started out as a misfire under load, i had inspected the spark plugs and had gotten plugs and coils, cylinder 3-4 are misfiring. on a cold start it would be fine, once you put any load above 2,500rpm the missfire worsens. compression tested all 4 cylinders dry=155psi wet=160psi. is there a way to clean the injectors?


Thank you for your help.
