Got the burban going had a broken sunshell in the trans changed it out along with a flush and she is as good as new now truck has a check engine light on on the led that came with the Nelson performance harness I'm not running rear o2s and no egr so it's possible my tunner did not delete them but the engine ran a little rough today so wondering if are since it sat up for a few months my injectors are throttle body could be gummed up
