The truck is great, I posted a long thread in the general discussion board but after 3 mechanics gave me different responses I wanted to come here and see if anyone has had the same issue. If you were a grandpa and drove around all slow then you would never know there is an issue. Rides smooth, no codes, great. If you were to try and pass someone then you will notice something is not right. The truck will not go past 3k rpms. Just gradually speeds up but no power. Where’s the v8? One person said fuel filter, the other said 02 sensor. The dealer said secondary air injection system and tried to charge me over $3500 for the fix. Insane. I’ll just sell the truck if that’s that’s case. Any ideas? Thanks in advance.
