I have a 05 GT that recently started running kind of rough. I replaced sparkplugs, coil packs and now injectors. It runs decent when I get on it, it's just the idle that's really bad and the engine is shaking a lot. I pulled codes and it told me system 1 is too rich and system 2 is too lean. It's also popping at idle.. What can cause this issue? any help is appreciated.
