Hey group, the other night I got the check engine light come on. I was close to an Autozone so I stopped and had them read the codes. Came back as "dirty fuel injector/injectors". Put some Lucas injector cleaner in the tank and went on my way. Light went out a while later that night. That was 2 days ago and then today it came back on again, ran codes at home and came back with "bank 1 running lean". So I am thinking that the injectors need a good cleaning. Truck is running great and getting 14 to 15.5 mpg according to the DIC. Put a can of Seafoam in the tank this afternoon but I know that is just a band-aid. What is a good way to clean the injectors without a complete tear down of the fuel system It is a 2007 Yukon Denali with 213,000 on the clock on a 6.2. Thanks.
