thue0824 Posted December 30, 2021 Report Share Posted December 30, 2021 Hi guys I'm new to this forum. I just bought a 2010 limited with a 3.5L. I am having an issue with rough idle and some hesitation while driving. I pulled the codes and it came back with p2196 and p2198. I have changed the purge valve, oxygen sensors, and fuel injectors. I have also used some carb cleaner to check around the intake for vacuum leaks to no avail. I'm really at a loss right now and am going crazy trying to track this down. Any help would be really appreciated. Thank you. Quote Link to comment Share on other sites More sharing options...

DILLARD000 Posted December 30, 2021 Report Share Posted December 30, 2021 Welcome to the forum. TroubleCodes p2196+p2198 = Fuel~Air Mix Stuck Rich Left+Right Banks. How many miles on Vehicle\Engine\Tranny? Has PCVValve & Plugs been renewed, Coils Cleaned+OhmChecked in the last 100kMiles? Is AirFilter clean & AirIntakeBox+PassageWays clear of trash\nests; rodents love to make winter homes in engine bays. Has ThrottleBody & IntakeManifold been cleaned in the last 100kMiles? 2 Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted December 31, 2021 Report Share Posted December 31, 2021 mileage? maintenance history as above? when codes happen, start with the simplest possible reasons. combustion is fuel + air + spark. you have not addressed spark yet. although not common on the 2010 MY, i certainly hope the PCM is not fried. 1 Quote Link to comment Share on other sites More sharing options...
enigma-2 Posted January 1, 2022 Report Share Posted January 1, 2022 (edited) Deleted original post. Passed over where you replaced the purge valve (usual cause). Possible vacuum hose leak? Edited January 2, 2022 by enigma-2 1 Quote Link to comment Share on other sites More sharing options...
