97 coupe jerky throttle loss of power
 

what could be causing my car to jerk when i apply throttle and for it to have no power? and in higher gears has nothing had trouble getting it over 70 hmm i also had my exhaust replaced and it was driving awesome then just turned to sh*t againhttps://www.hyundaiaftermarket.org/f.../banghead2.gif

Are there any stored codes in the computer?



Did the exhaust shop disconnect the battery while working?



If you tap and tug/rotate on the throttle position sensor, what happens to the idle quality?
