I’ve got the 06 Gmc with 5.3 engine with 185,000 miles on it. Runs good but i’m getting a rich idle code on right side. I’ve replaced the 02 sensor but still get the code. It goes and comes. Fuel pump was replaced 10,000 miles ago. I run a bottle of fi system cleaner through it and the code doesnt reappear for a month or so. I guess maybe it has a leaky injector or more. Who offers injector testing and cleaning services? Or is chevron with techron the best cleaner in a bottle you can use?
