Intake problem
Hey, y'all! My 2009 has been throwing codes P2173 and C121C after I changed the throttle body. I checked for vacuum leaks and found nothing. I also checked the map sensor and harness, finding no issues. When the codes throw, the Jeep goes into a rough idle until I clear the codes. It only happens on the warm-up cycle. Has anyone had this issue, or does anyone have a solution? Thanks!
