Cherokee Misfire Code
Recently took the ol XJ to get inspected but on the way to the garage it threw a check engine light. I hooked it up to my little scanner and read the code which came up Misfire on number 6 cyl. Most guys posts have a number 3/4 cyl misfire due to heat soak but i havent heard of anyone getting a number 6 cyl misfire. I tried running injector cleaner through it but nothing. Every injector fires as you can feel them and they have a slight tick to them (normal? I dont know). Im going to do plugs in it (NGK copper core) thats what everyone says. Anything else to check? Its a 98 and has 128,000 on it and the head is probably not cracked (oil was just changed and was good, temp runs a hair below 210, coolant is good). It probably has the 0331 head on it. Any input would be helpful, Thanks guys

tic is normal for the injector. have you checked spark on that cylinder? Probably dont have a 0331.

you can check though by looking between the 3rd and 4th intake ports on the head.
