Replaced tps switch, coolant temp switch, fuel filter, mas air flow sensor, air filter, new plugs, used sea foam in tank, new gas cap. If you try to hold gas pedal at 2000 rpms, the engine races to 2500 then back down to 1500 then back up again etc. Wont idle, goes up and down just not as severe. When driving it boggs down with no power at alll (stall) then it will pick up again! Any magical thoughts?
