P1125 tried almost everything
I've been trying to get rid of P1125 and I changed the TPS,APP, and throttle motor, then cleaned everything and repaired some damaged wires also pins yet no luck after my car starts to warm up my throttle goes away. I've tried almost everything and I can't seem to fix it I even cleaned the ECM connections

once it warms up and you lose your throttle, access your ecm and tap on it a bunch while watching the tps voltage on a little scan tool. see if it changes. its possible you have a bad ecm. but, usually when things start failing with heat, its resistance related. like bad wiring or bad grounds.

It might be bad wiring. I experienced this issue before I sold my GS400. I had it for 3 years replaced all that you mentioned above. Still I was having problems with the TBA. The guy I sold it to still complains to me about the issue. lol I told him all the issues before he bought it.
Look at the pin connectors see if you don't have a open terminal that's too far open. Could be not making contact with the pins.
