i have a 92 Honda accord Lx 5spd and when i let off the gas or sitting at a light or stop sign my car idles really low at around 200 or 300 Rpms but sometimes it will runs right around 7or800 like it should be but when it idles low sometimes it shuts off at randoms times....its been doing it more and more lately....any ideas

 

A dirty, sticking Idle Air Control Valve (IACV) will cause these symptoms. Remove IACV, clean inlet screen, valve movement, inlet/outlet ports. Also clean both sides of throttle plate and throttle body bore near throttle plate.

good luck
