Hi lads, my S4 is having misfires on cylinder 4 but only after hard drive, engine must be really hot to it to manifest at wot.
After cruise for a little while to cool down it stops misfiring.

I already swap sides coils, icm, injector and plugs.

Still misfiring on cylinder 4

Fuel trims are in spec at ~2.5%

Dtc only regards misfires.

Strange thing, vcds and me7logger are occasualy showing diferent cylinders misfiring, on this logs for example, it shows cylinder 5 but vcds cylinder 4.
Had it showing previouse cylinder 5 on vcds and 4 on logs.


Any ideas of what could be causing this?

Best regards
