Throttle issue

I have a 96 cherokee with a 4.0, I6. I have been having problems with it hesitating or dying when I give it gas. It seems to only happen when you just touch the gas, but if you give it lots of gas it is fine. It has no problems past just touching the gas as far as accelleration or hesitation. Today I checked and replaced the cap, rotor, plugs and wires. Still happening. I am thinking maybe throttle position sensor? Anyone had the same problem or able to help diagnose? Thanks

Way unlikely...I had a problem with the wires to my injectors grounding, a little sometimes. It would take off fine if I punched it, but shudder and all sorts if stuff just trying to cruse. An easy check....

Also there is some business with the vacuum and the fuel pressure...that I really don't quite get..

Test the TPS. Mine would would go down the road fine. When you stepped on the throttle it would start to go and then hesitate like your foot slipped off the pedal and then you stepped on it again. Did that every time I'd shift. In 1st gear it would almost make you face slap the steering wheel.
