I have a 2007 trac with a 4.6 4x4 with 6r60 trans. I bought the truck used a few months back and I am having some sort of issue I cannot seem to find an answer for. While driving the truck at around 40-60 (give or take) the truck rpms seem to surge up. I barely have my foot on the throttle and nothing is changing. It will go from around 1150-1200 rpm to around 1300-1350 (again give or take) for a split second and then right back down. Whilst this happens it seems to have something that feels like torque shutter but only when this happens. If I gas it it will go right on no hesitation. If I turn O/D off this doesn't seem to happen. Possibly because the RPM at that speed is around 2k not 1.1k.
Things I have replaced so far (new parts)
1 Plugs
2 CoPs (all 8)
3 Injectors (all 8)
4 Fuel Filter (twice)
5 TPS
6 Pulled the throttle body and cleaned around it
7 Beating my head against the wall
8 Voodoo and small animal sacrifice
(7 & 8 were my last resort)
Any help into this would be great. If I left something out or need to explain it better please let me know.
