2005 Buick Allure Check Engine Light
2005 Buick Allure, made in Quebec. I have to buy Lacrosse parts in the USA. Have changed cadcon, 2 sensors upstream and downstream. CEL still came back on. Just went and bought a new gas cap, filled tank with highest test gas and added a fuel injector cleaner. Need that light off for NYS...- GrewUpBuick
