I think my TPS is going? to anyone that might have an idea, especially you X charger guys, Here lately when my car warms up it stalls when I push in the clutch and the car idles down, some time it goes down past 0 on the tach and low oil pressure comes up ( I think thats cause engine stalls ) good news is it fires right back up and go my way, when its cold I have no probs. when its warmed up and I turn the motor off and start back up it doesn't want to idle unless I pepper the the pedal to keep it running, then its fine, I've been told by the dyno guys mustangs don't always throw a code when TPS is going bad? any ideas? my Ford dealer told me they will replace TPS under warranty unlees they can't get screws out, then they will replace the whole throttle body.

The FI runs under ohm resistances. Hot is one resistance and that has to be in spec with cold is it specs or not it is gonna spec out ohms wise.
I wonder if they say it's the TPS, change the gasket with the unit and there it runs so good now is did you check the gasket for leaks? Expand she is hot to open an air gap. Cold she is contracted is the gap is narrow and lean is poor to no idle.

Intake manifold hoses from the sucking of the engine is exposed to air, she is a closed loop more or less. So air from a cracked hose to a burned out gasket from heat cycling is it has to be one or the other.
The car starts to well to have a unit going down; but you never know.
