I have a 2000 infinity QX4, V6. The truck has recently started to run rough at idle in cycles. The truck starts fine and idles fine for about 1 minute, and then it will idle rough for approximately 30 seconds and repeats the process of idling fine for 1 minute and then idling rough for approximately 30 seconds. It will only do this at idle. I checked to see if it was due to the AC compressor kicking on, but the AC Compressor never did. I also checked for Vacume leaks and didnt find any.
