1991 Z24 manual stalls

This crazy car will idle normal for 10 minutes or so and then revs up to 3500RPM's and then just stalls. Then when I am driving, I will go switch gears and the RPMS will stay up at 3500RPM's or so...(like the throttle is sticking)it wont idle down. I cant get the motor to react properly. Plus the car is super jerky...I had it diagnosed and there were no codes. I changed the plugs, fuel filter, oil, put injector cleaner in the tank...Can someone please help. The motor is the 6cyl 5speed manual trans. Z24

That throttle body is notorious for getting gummed up quite nicely. I'd take that TB off, then take a nice can of carb cleaner to it.

Other than that, TPS might be going out.
