Thanks for bringing over the uber monitoring tool and taking a look. I think we've narrowed the field on why my daughters TJ is running like junk.
When I got into it and saw how bad the spark plugs were I won't be surprised if there were some coil issues. Having a questionable injector is also not great. Maybe it actually is the CPS but that still sounds kind of sketchy to me seeing that it was just replaced.
Anyway, I appreciate the help. Good to know we have some motor skills in the club. I can fab and work through suspension issues but motors I usually leave to the professionals.
