Q: Irregular revving

asked by在2016年8月20日

Good day, when I start my car the revs goes to 2000rpm and slowly comes down. When I drive and stop at a traffic light it idles at 2000rpm. When I engage in a gear and release again it returns to just under 1000rpm. Also when I drive 40mph and remove my foot from the acceleration is feels like is jurks a bit. Please help. I have replaced the throttle body incl the TPS sensor as well as the MAP sensor. Regards

My car has 161500 miles.
My car has a manual transmission.
