not my first manual so i know that there is some jerkiness with driving stick, but the car jerks HARD when going on or off the throttle. Its more pronounced in lower gears, but definitely still exists all the way to 6th. I also have idling issues, have the p0507 code and at stationary the rpm bounces from 1k-1200 and when coasting in neutral it surges to 2k ish and goes down once the car fully stops. I have a feeling they are connected bc of other things ive read abt the tps sensor and how easily they go out. I dont think its mounts, visually fine and no excessive shaking at idle although they are slowly on their way out. The jerkiness is kinda like one large lurch like if you shift too fast and if i press the throttle and depress it a few times in lower gears quickly it shakes like crazy. Rpm doesnt appear to change when it lurches. I have taken out my idle air control valve and cleaned it although it doesnt rule out the possibility of it being bad. Have also done the idle relearn procedure to no avail. Any help?
