4.0 is cutting out, help!

1987 Cherokee, 4x4, 4.0, 3.5 lift and 33x10.5 boggers. was running fine until i put the boggers on it last week, but i doubt that has anything to do with it. if i gradually lay onto the gas, the motor wants to spuder and cut out, however if i nail the gas, it does fine. fuel filter is good, its getting gas through the fuel rail, and i just changed the plugs last week also... maybe my injectors are crudded up, or something else? any input would be great, thanks!

upgrade in tire size? gearing?

gears are stock, i went from 33 12.5 BFG AT's to 33 10.5 boggers...

your tps may have a dead spot

hmm tps could be it...

I am experiencing the same problem kinda, Only mine does it between 50-65MPH and onlyt when I am barley on the throttle. If I get out of it it stop or if I give it more fuel it does it. It feels like it is "bucking" but When it does it I see No change in the tach, Battery guage, Temp, Oil Pressure.
Is there a list of the sensors that are on the 4.0L?
