Just going to start from the beginning in chronological order.
Bought truck two months ago, repaired both exhaust manifolds right away since they were both leaking.
Diagnosed a rattle in the exhaust as the resonator.
Truck has a loss of power, 0-60 goes from 7.2 seconds to around 9 seconds. Loss tends to be most noticeable at 50% to wide open throttle.
Have resonator cut out and replaced with straight pipe and fuel filter changed. Fuel filter was almost completely plugged. (Loss of power still remains though)
On the freeway today I accelerate to wide open throttle to pass some guy doing 55 in the fast lane. During acceleration my check engine light comes on and flashes for 10-15 seconds and stops. I then give it full throttle again and my truck accelerates like it had full power (first time in a week or so), it seemed the transmission was more aggressive all of a sudden, like it downshifts two gears instead of one at wide open throttle. Kept giving it full throttle and it was working great, except their was an obvious surging at 50% throttle or more. Like the truck was jerking back and forth (imagine flooring it and letting off a little bit and flooring it again constantly).
Later in the drive I floor it and there was a screech, loud clunk, and it felt like my truck hit a wall all at the same time. Kind of felt like a gear slipped in the transmission, my guess would be 4th since I heard it downshift two gears when I was in 6th doing 70mph. Floored it again and it didn't do it. Drove normally all the way to school.
Drove home from school and it reverted back to its loss of power. Also I noticed that the surging was much more apparent, at 50% or more throttle the surging felt like my truck was fighting itself.
Is my truck possessed? It feels like it's possessed.
