I could be on the wrong subforum but regardless, I have a 2001 IS300 2JZ VVTi engine swapped into a different car.
Like the title says, my engine has a rpm lock directly on 4K. Apart from this, everything works fine, though occasionally I will have a CrankShaft Position Sensor and CamShaft Position Sensor code pop up and then go away after a bit on its own. Ive replaced everything (to my knowledge) that could be related like the PRNDL Position Switch on the original trans, Throttle Body, Multiple Factory ECU's, and the MAF. It should be worth noting that the lockout is in all gears.
According to the engine shop I bought this engine from, it has 55K miles, factory oil changes, and no mods. The normal stuff. Does anyone know what I can do to fix this (apart from buying a aftermarket ECU) or lead me in the right direction?
