My 99accords idle fluctuates whenever i turn on my heater fan ,ac,headlights ect. When its coldvthe fluctuations are so bad that the motor sometimes stalls out it also sputters/missfires at the higher rpms. Example taking off with medium or higher throttle it missfiresjust when its about to shift from first to second gear. It also seems to have very little power.

Arbie, As a first step have scanned for trouble /diagnostic codes. If your engine is most noticeably running rough with an accessory on, have the belt checked for tension/slipping/wear, battery and alternator checked as one or the other may be faulty. Also check and clean all wire connections,clean and secure them. Vehicles engines can run rough when not getting sufficient voltage.

Hope this is of help, good luck.
