2003 Buick Regal GS 6 Cyl 3.8L
Engine miss poor fuel mileage
The good year dealer could not diagnose problem. One mechanic told me sounds like a fuel inkector stuck open. I am wondering should I go with Injector replacemnt, and if that doesnt solve problem what is my next step?
First step - have the check engine light or stored fault codes scanned - for free - at any local auto parts store; Advance Auto, Auto Zone, NAPA. Then, post a reply as 'add answer' with the specific fault code for more assistance.
