Pull a compression test on your cylinders. These engines are just about bulletproof, but I've seen several of them with bad head gaskets. I had just about the same problem on my 98 Jeep Cherokee Sport. Turned out to be a bad head gasket between number 2 and number 3 cylinders. Fairly easy to replace, just a PITA.

If God didn't have a purpose for us we wouldn't be here, so
Live simply, Love generously, Care deeply, Speak kindly.
(Leave the rest to God) 
Silence, in the face of evil, is itself evil. Not to speak is to speak, not to act is to act. God will not hold us guiltless.
