Do anybody know the symptoms of a bad tps? I have a 95 240sx.

With my car, everytime MY car is running.....the idle is perfect and when I try to tap the gas a couple of times to rev it up, the car would bog!! and stumble...etc... and i would have to floor it to bring the revs up, and while the rev's are going up, the car would bog and the revs would fluctuate....and you would hear pops from the rear of the car through the exhaust.

What have I tried?, I"ve did a fuel injector addictive cleaner, fuel system addictive cleaner, changed the fuel filter, checked my timing, and cleaned my throttle body. The car's drivibility is so bad that when I let go my clutch (in every gear) it would bog and rev's would fluctuate!! and die if i dont rev the car really high. I even checked the fuel injectors by spraying some throttle body cleaner spray into the intake pipping's feeder hose that goes to the valve cover, to see if the bogging/rev flucuating would stop while spraying and reving.....but it still continued. I dont even drive the car. The car have been sitting at a small body shop and probably been moved a couple of times to in and out the shop, and I just got the car back a week ago and been dealing with this problem evere since. Before the car was brought to the shop, the car ran fine and everything.

I"ve read the ecu and it throw codes 12 (maf sensor),34 (knock sensor), and 43 (tps sensor).

I also swapped my maf with my friend's maf that has a s14 too, and it still is running bad. I dont even drive the car because I have to carefully rev the motor high or eles it would bog, rev would fall, and then die.

Through the process of elimination, I think it is a bad tps sensor. I had a check engine light for my knock sensor and that didnt effect the drivibility of the car and I've swapped my maf with my friend's maf and that didnt work.

please help anybody?
