Hi, my name is Jay

have you tried a new TPS? The air charge, ECT, map and TPS sensors all share the signal return wire to computer and the TPS is the only one you have not changed. If you cleaned throttle body then you may have got cleaner into the sensor through the throttle shaft and shorting it out.
