My 2000 B18C (GSR) motor has taken on a strange behavior recently, I hope someone has some advice.

This happens randomly and seems to be more often when the engine is cold (below running temp)

The engine acts as though there is no middle-throttle. It's either accelerating or decelerating, there is no "sweet spot" on the gas pedal where the engine just maintains rpm.

In first gear it is VERY noticeable because the car jerks forward and back as the engine goes from accelerating or decelerating, depending on pedal position.

Other then this weird occasional behavior the engine runs fine, this is QUITE annoying and would LOVE some advise if anyone has any!

Thanks!

 

first place to start would be the TPS. With the car in the on position use a voltmeter to measure the volt at closed and throughout the range to open. it should be a smooth transition to full voltage. Read a chiltons manual or google for information on the voltage readouts and the pin outs

Edit: saved you some time. Just searched TPS on the HT search engine

Thanks for taking the time to reply, I will look further into this and report my findings!
