Spitting and sputterring
I have a 2006 f150 5.4 scab 51000 miles
A few weeks ago got a CEL took it to dealer they replaced cop and plug on cylinders 4 and 5 . Truck had been running like crap. Missing backfiring poor mileage etc. Got truck back still not right. Took it back they came up with a p41 code and did an injector on cylinder 8. All this under my extended warranty. Truck still isnt right. At wide open throttle between 3500 and 5000 rpms it misses and surges and kinda chugs. Its not noticeable at all at lower rpms. Truck is showing no codes and dealer is getting argumentative. What things should i be looking at? Any help would be greatly appreciated
