Just purchased the 98 Jeep. It will start but will not idle on its own. I must feather the gas until the engine starts warming up.

Will then idle & run normally. Does not miss or run badly, just goes to 0 RPM's when it sits overnight and I first try to start it. Restarts ok but wont run normally until arm.

Could this be a TPS? I've heard talk of ASD's doing this too but I'm just guessing.

Any thoughts will be appreciated!
