Tilteduk Posted September 27, 2016 Share Posted September 27, 2016 When I'm coasting along in gear and just letting the car pull itself when I go on the throttle lightly the revs drop and go back to normal which is causing a jolting motion. When the engine is running and I'm stationary and tap the throttle a little the revs drop also? When I'm driving and want to stay at a speed limit, I have to be on the throttle or off it there's no in between? PLEASE HELP ITS DRIVING ME CRAZY Quote Link to post Share on other sites
5T4R7ET N/A Posted September 27, 2016 Share Posted September 27, 2016 Clean out the throttle body and make sure the cable is not catching anywhere. Lube the part that has the spring and make sure it flicks back fast and smoothAlso could check TPS to see if it needs calibration. Pretty easy to do. Quote Link to post Share on other sites
