I have coolant that appears to be coming from behind the water pump on my 98. It's dripping from the lower hose but I can see that it's coming from up the pump near the block. Is it normal for the seal to go bad? The water pump is only a couple years old.

Depends who made it/remanufactured it....
ok so i bought a 96 cherokee with 232k miles on it it ran rough when i bought it and i did a tune up the tune up cleared it up greatly. i also fixed the exhaust leaks and anything i felt that needed to be done, but i cant seem to get rid of the miss fire on cly 1 and cly one only i did a compression test and all the cly are 140 to 165 which is great im at a complete loss as to what i can do. this is my 5th cherokee so i know my way around them just this issue has got me stumped. (side note the miss is only at an idle cold or hot it doesnt matter )

I don't have an attitude im just letting you know that I stated in my first post that i mentioned that I did a tune up ive actually changed everything twice just to be extra sure im sorry if it seemed like i have an attitude just trying to figure out what i can't get rid of the misfire
Ive been going through everything i know jeeps are known for and still nothing ive done what you said and more i just keep getting the code multiple missfire and the misfire cyl 1 code ive changed the iac , tps, plugs, wires, cap, and rotor i also had a purge valve silonoid code but i changed that and it went away
