1988 Wrangler 2.5l 4Cylinder

Hi all. I am having issues with my 1988 Wrangler 2.5L 4Cyl engine. Starts up great, then as soon as it gets up to temp. it starts stalling out and if you hold the accelerator at one point the engine will just keep hesitating and tries to stall. Put new TPS sensor, MAP sensor, and Crank Shaft sensor in. Still happens. Eventually it will idle fine at around 900 and then runs like a charm, but as soon as you turn it off it goes back to stalling. Sprayed a quick spray of carb cleaner in the throttle body when that was happening and it started to idle fine again. But as soon as you turn it off it goes back to hesitation. Any help on this one would be greatly appreciated
