Replaced TPS Still surging. Pulled the IAC at same time and cleaned it.
Cap, Rotor, plugs & wires changed around 50K miles.
Radiator recently replaced.
Condition
When I just starting driving after startup, The jeep will surge with moderate throttle at low speeds. Like it has no power, trys to stall. It stops surging when I mash the throttle and let back off, then drives normally the rest of the trip. Shut down for 30minutes start back up and the surging repeats until I mash the throttle again. What do you think, Vacume? Fuel Pressure? Clogged Cat? Map? IAC? Bad replacement TPS? Computer program? Transmission? CTS? What would you check next? Thanks. Tried search but didn't find anything that went away with high throttle.
