99 4Runner starting and running issues
I have a 99 4runner with the 3.4 motor that I recently replaced. Ran fine for two weeks but a few days ago it suddenly died while driving down the freeway. After attempting to restart it would fire but not run. After cleaning the ground on the intake it ran fine again for a few days but again it fires but doesn't run. When it does run it sputters when you rev it and when driving anything past 1800rpm it bogs down, switches gears then bogs down again. Replaced the MAF sensor, both o2 sensors, fuel filter, checked all vaccum lines. None of it changed the way the motor runs. Even made sure the cat was good. Im at a loss at this point what it could be. Throws codes p0110 and p0505. Any help would be greatly appreciated.
