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?

This is from the manual. You take off the intake and there are two ports as you look in.

6. Put your fingers on the lower port (A) in the throttle body.
A
Does the engine speed drop below 700 1 (750) 2 rpm?
YES-Check the idle speed with a different load condition (electrical, A/C, gear position, P/S etc.) (see page 11-348). If it’s out of specification, replace the IAC valve (see page 11-412).
NO-Check for vacuum leaks at these parts.
• PCV valve
• PCV hose
• EVAP canister purge valve
• Throttle body
• Intake manifold
• Brake booster hose
• Intake air bypass control thermal valve

I've never smoke tested, but spraying those parts with some carb clean will cause th motor to change as it gets sucked in. Not sure how to post the pics from manual.
