Car went into limp mode one day while sitting at a light. Ended up doing spark plugs, coils, injectors and a fuel system clean. Originally had a code for cylinder 1 misfire and injector code for cylinder 1. Now after changing all that it has a rough idle and hesitates when you hit the gas after letting off. It now has codes for fuel system too rich bank 1 and fuel system too rich bank 2. It gets worse as the car warms up. I am going insane. I would appreciate any input please!!
