My 2000 Rav4 idles rough. This happens mostly when it is stopped in Drive, the AC is on and when the radiator fans kick on. Scanner showed no codes. I noticed a noise from the Alternator when this happened, and found that the voltage dropped when the fans kicked on, so I replaced the alternator, but the problem persisted. I also cleaned the EGR valve with intake cleaner but the problem persists. I can find no apparent vacuum leaks. I would really appreciate your assistance.
