The Throttle Position Sensor can get out of adjustment due to wear in the throttle body or due to carbon build up. This will cause the idle timing to advance more than 30 degrees which will cause very high HC and NOx emissions. Conversely, the Throttle Position Sensors can wear out and not properly advance the timing which causes a lack of power and poor fuel economy.Google+

not fixed still working on it the mechanic has it. it stays reved up in a high setting. even when you start off from a red light it sounds like am tring to race the person next to me.
lose of power/throttle. cleaned my throttle body and replaced pcv valve. also air intake hose.
idk if it's the throttle sensor or bad timing on the camshaft.
it doesn't seem to want to go from a stop. it starts pulling, then mid way tru the first gear it looses power but continuities to rise rpm and slowly regaines power. 3000-32500 for first gear to shift without putting much has on the pedal. 2nd gear seems normal but not more power/torque. 3&4 gear the same but seems okay.
just the feeling of not enough power to pull the car even when pushing deeper down on the pedal than normal driving manner. pls help. also lose of feul economy
