I've got a 2018 Colorado LT V6. Started after I changed my battery. Now the engine misses badly, check engine light on for code 171 lean on bank 1 and this can be mistaken for a misfire. It starts off with the misfire and then my Stabilitrak and traction control light come on along with the check engine light. Just tried to go somewhere to see if driving it would help it was missing worse than it was and the check engine light started flashing along with the stabilitrack and traction control lights on. I recently bought a Launch CRP919. Waiting for it to show up. Going to reset BSM and see what happens.
