The engine kinda stumbles until about 3 grand or so when I rev it. Like pfft,pfft,pfft,then VROOM!This makes it kind of a pain in the *** to take off smoothly from a stop. Also, if i'm cruising,in say...3rd gear the car will start to buck after a bit. Then ill have to push the gas harder or push the clutch in and release it to get it to go back to driving smooth again. The car backfires bad sometimes if i'm in 5th and let off the gas. Up until now the car has been pulling strong. Just for the hell of it, I pulled the plug apart and tried to rev the engine and it wouldn't rev. The car will also die if I stop at a light without holding the gas peddle. This sound like a miss adjusted TPS?I am going to do a diagnostic on it, but just wanted to get a few of your opinions on the subject before I do. Thanks guys.

I forgot to add, that if I screw with the adjuster screw, the car might act better for a little while. Then right back on its face.
