No, but I think changing fuel helped. I switched to Shell and 76, from costco gas. I have put Techron in, Bgk 44 and all all types of additives in thinking it may be a Fuel injector. (no codes though) I was going to change the knock sensor, but havent gotten around to it yet. I get some ping/knock when in drive, under a load (like giving it gas starting to go up a hill). I assume you have the same rough idle issue? What have you done to trouble shoot?
