my car is having similar problems to the guy who posted about his 98 bogging down and having rough idling/stalling. my car will randomly shut off while idle at lights, and sometimes while driving ill lose throttle response. to counteract this, i had to set my idle manually to have it sit around 800-1000, and its turned wide-open. i checked my sensors, tps is fine, had a problem code with idle control and 1st O2 sensor reading wrong. i recently did timing belt, plugs, wires, coil pack, cleaned fuel injectors.

any help would be appreciated, thanks.

 

its your tps or tps wires and connector most likely

 

thanks, ill check those out asap.

 

My 1999 tiburon idles between 1500-2500 rpm's when I put in the clutch. When I come to a stop the idle sticks at 2000-2200 rpm's. Tonight the check engine light came on steady. Can you help me?
