99 maxima SE 5 sp, rough Idle

[jonbeder]

I have a 99 Maxima with 155,00 miles. Recently had a coil replaced because of skipping and computer code. After recent replacment of clutch and fuel filter car developed a rough Idle but otherwise runs great.

At Low idle with AC off smooth as silk, hit the AC button which raises the RPM a bit idle becomes rough. Always loved the smoothness of this engine. Diagnosis-Cure?Thanks for you helpJon

Start by performing a base idle inspection. If its low you may have carbon build up in the idle air control valve. I have found trickling in some throttle body cleaner through the air bypass hose with the car running helps remove some of that. You need to T it into the line not completely remove the line to do it. After performing this set the base idle to spec.
