Hey everyone. Just bought my dad a 2000 Explorer Eddie Bauer 4.0 SOHC V6. I absolutely love it, its a great vehicle. 257,000kms with a rebuilt transmission, new spark plugs and a new exhaust. Got the entire truck for $850!!!! Only problem is as follows:
After the truck warms up a bit, and your sitting at a traffic light, very rarely it will have a rough idle for maybe 1 second, and it will go away. Also when you feel that rough idle and step on the gas, it stutters when getting up to speed.T his only happens once or twice for the entire time you're driving. If you're on a drive that lasted maybe half an hour, it will do this idle thing only once or twice. Even with this though, the engine has lots of power and doesn't bog down or stall. After reading all the posts about intake manifold gaskets, im getting a bit scared that it might be that, but those are mostly on cold starts, whereas this truck is perfectly fine when its cold. Any ideas? Thanks in advance.

EDIT: Theres no check engine light, and i cleaned the MAF sensor and it improved the problem a bit, any ideas if a bad MAF can cause this?
