Cleaned throttle thoroughly as suggested, with Seafoam. Nothing changed. Pulled 6 codes at Autozone. 4 of 6 transmission related, P0700.P161B, P0730, P0777, P0113, P0420.
Did not perform Fuel Pressure check. Yet. However, drove the usual distance that it takes before the vehicle begins to fail as I describe. Parked vehicle at home and took idle up to 2000RPMs and held it steady for 15 minutes(in park). Allowed engine to settle to normal park idle. Revved engines 10 times. Engine responsive the entire time. SHifted the gears from Park to Drive 10 times. Revved engine. Engine remained responsive. Backed the car up about 50 feet, put car in drive and drove back into parking space. Repeated this and by the 6th time in DRIVE and REVERSE, the FAULT condition appeared. Pressed the gas pedal to floor, no engine response, held pedal to floor and counted 3 seconds before the engine began to rev slowly then shot up tp 4K and the vehicle lunged forward. Parked the vehicle. Pressed gas pedal, FAULT condition remained. Shut engine off, pulled key out and opened door(simulate exit). Restarted engine. Pressed gas pedal, ENGINE RESPONSIVE. Put car in reverse and repeated to drive in reverse and Drive until FAULT condition reappeared. On 3rd reverse the FAULT APPEARED. Repeated process, turning off engine, etcetera. Each of 4 times the engine was responsive after the engine was shut off and restarted. Keep in mind the engine was thoroughly warmed up, outside temp was about 28*F, It was as if I was resetting the system.
Final note. Transmission has never been serviced(No fluid change or filter change) in 150k miles. Does not leak fluid. Leaning towards changing TXoil and filter(and very carefully, I might add). This is a CVT.
