Well trouble free so far but now I have an issue that I have no idea what it is. It started a few days ago that while driving if I floor it, it will not go over 3000rpm. If I let off the gas it will downshift back to normal rpms. But also it didn't really want to go over 55. The truck has about 110000 miles on it. I've had no problems yet and my oasis report came back with no work done. Previous owner said the egr delete was done but that would be the only mod of that nature. Any help would be greatly appreciated.
