01 grand motor problem. need help

posting this for a buddy.


I have a 01 Jeep Grand Cherokee Limited. I have about 77,000 miles on it. I hate to trade vehicles. I really do. I know I will have to one of these days but it is an easy thing to put off.
-
Problem I have started to notice is that there is a very slight and minor hesitation or hiccup when I am cruising down the road at say 65 mph. It is hardly noticeable but it is something that is bugging me. I would say in a mile, I would notice it do this about 3 or 4 times. Do you think the brains may be going out of it or could it be as simple as the fuel filter? Perhaps an ignition control module? I am pretty much illiterate when it comes to mechanics. Any ideas? I don't want to take it to the shop and then have them take me.


thanks guys ill let him know what you post. thanks -chris

I would be willing to bet a simple tune up would fix it. (plugs, air filter, flush fuel system)

If you don't know when the last time you performed each task above, you really need to...

If you're running your air conditioner it just may be the clutch of the compressor kicking on and off. My 2001 4.7 does this (very slight) when I'm cruising (60-70 mph) on the open road.

This may solve it, but it is most like as below, or maybe a bearing going on the water pump or alternator, all causing more stress, taking power away. But that seems like it would be a little more of a constant powerloss than the AC.
