Title: Misfire Post by: armageddon on June 03, 2026, 12:35:12 PM 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 |
