alright guys, just recently, my gas pedal/throttle has been acting funny... let me give you the low down.... FYI motor is a S13 Blacktop SR

when i first crank my car in the morning and drive away, everything is smooth, and even, then it gets to operating temp and the throttle is jumpy.. ya know right when you push the pedal for a "cruising" speed? well that little sweet spot is no longer there, it's either no gas, or accel, and it bumps like that while driving, so i had just hold the pedal in the sweet spot anymore, is either coast or GO, but it's not like WOT, just as if i have the pedal down a tad past "cruise"

so ro reitterate, if it's not "coasting" it will go (with a slight bump) into accelerate... my "cruise area is gone, but only AFTER the car has warmed up..

here's my possible theorys....

A. Throttle position sensor, once the coolant warms the TB up, the TPS goes a little haywire..

B. clutch not grabbing, although it is a ACT unsprun 6 buck, with fidanza, it should grab like a mofo, and only has about 300 miles on it... but when cold, and preengagement, it will make a whine/grinding noise (throwout bearing not greased enough whine most likely)

C. a catch somewhere either in my gas pedal or throttle cable, but that REALLY wouldn't explain why it doesn't do it when cold... on at operating temp...

i'll be going outside in a few minutes to put a volt meter on the TPS, check the throttle cable, and the predal... ANY input would be greatly appreciated, as this isn't a MAJOR problem, but it kinda sucks driving around town, and only having "coast" or "accelerate" with a "dunk" sounds as it transitions...

thanks guys, and on with the suggestions!!!
