Ok so I have a little problem.
Sometimes when I start my wj it idles real rough and when I put it in gear it is real choppy on the power and jerks and if you give it gas you can hear it backfire through the intake.
If you punch the gas it almost cleans itself out and runs fine after that.
Anyone have any ideas?
I changed plugs and swapped coil pack. Tried putting in some fuel injector cleaner. None of which seemed to help.
