Going to go with fuel system treatment for a few tanks of gas. I run Arco in everything I have and have had no problems. I run it in the C6 Corvette, my 82 Blazer, my 99 Jeep, my 55 Chevy. Next treatment will try the Berryman B-12. Thanks for the info.+1 for the code(s). There are no monitors specifically to tell if the injectors are dirty. Yes, clogged fuel injectors could cause a lean condition. But, there might not be an actual failure with the injectors and the DTC could be a failing O2 sensor erroneously reporting Bank 1 being lean. A failing O2 sensor could also cause a lean (or rich) condition.
The DTC for the engine running rich or lean is determined by the O2 sensors. If the problem is isolated to one bank, a quick at-home test for the sensor is to swap it with the one on the other bank and seeing if the code changes to Bank 2 running lean. If your undercarriage is rusted, don't even try this unless you plan to replace the sensors. Other common causes for a lean condition (perceived or actual) are exhaust leak ahead of the sensor and intake manifold leak, although this one usually causes a rich condition.
As for additives, I'm a fan of Berryman B-12. It's about half the price of Seafoam and more potent. I run my tank to around 1/4 tank or less and add a can. I run it until really low then fill up. Unless running E85, I stick to Chevron/Texaco or Exxon. NEVER Shell. I use the B-12 every 3-4 refuelings.
Will have to look that up on line. I remember a long time ago I remember that you could run cleaner through the fuel rails. Seems like that would work the best.Pulling the fuel rails is not a hard job really, look for and clean out the clogged injectors, and install new o rings. Ive seen some videos on youtube where guys will hook up a 9v battery and get them to open and spray cleaner through them.

If theres larger debris inside the injectors, or build up of gunk then no amount cleaner you run through is going to do a very good job. The larger debris just cant get through the small injector holes.Will have to look that up on line. I remember a long time ago I remember that you could run cleaner through the fuel rails.

Just curious.... Why NEVER Shell?
just take it to a shop that offers a injector service they "should" have a machine that connects to the fuel rail and they run the cleaner right into the fuel rail with a adapter, usually runs about $80-100Hey 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.
