I need to try and hunt down a P0171 code system lean bank 1 and I figure the injector might be the issue. I was going to use this injector cleaner but I want to make sure that it won't harm anything else like sensors or what not by using this cleaner.

Any experienced insight is welcome.

 

The injector cleaner will not hurt at the advertized amount. I like to get shell gas because the regular has 3 times the injector cleaners than required by law, and the premium 'vpower' has 6 times the required cleaner! Lucas is great stuff and so are others but in my opinion its not worth the money unless you buy a vehicle that has been sitting a year or two or sits a lot. Not sure if injector cleaner would fix your lean mixture problem.
