did you recalibrate the tps sensor to the new ecu? did you check the static timing after you replaced the cam position sensor?

would the tps not reset make it just not feel right ,hard to describe

It's a little tough to decipher your posts (no disrespect if English isn't your first language) but it sounds like you did NOT reset the TPS after installing a new ECU? If not, that would be the first thing I'd try; I'll bet it fixes your problem...

people claim the tps reset as a cure all on here sometimes, but changing the ecu is one time you definitely need to re calibrate it.
