Starts up fine. No power while driving cold. As it warms, it starts to sputter , spits, then stalls. Not driveable. No codes or light. 140k Now, tuned up @ 110K. Known defects : oil plug seal gasket leaking. HELP ????

Having no codes brings an interesting set of challenges.

The things I'd try to address are:
1. Clean MAF sensor
2. Clean throttle body
3. Check crankshaft and camshaft sensors
But first, try to do the idle relearn procedure

Never hurts to clean. Was leaning towards replacing fuel pump & relay because of mileage. Cleaning is cheaper. Can I reuse gasket on T/body ? How do I do the idle relearn procedure ? ? ? ?

How do I do the idle relearn procedure ? ? ? ?

Try this procedure:

1. Turn ignition switch “ON” and wait at least 1 second.
2. Turn ignition switch “OFF” and wait at least 10 seconds.
3. Start engine and warm it up to normal operating temperature.
4. Turn ignition switch “OFF” and wait at least 10 seconds.
5. Start the engine and let it idle for at least 30 seconds.
6. Disconnect throttle position sensor harness connector (brown),
then reconnect it within 5 seconds.
