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.

Seems the idling speed is too high causing the problem.

Check the coolant level.

Check the IAAC valve operations.

The IAAC is the Idle Air Control?
