Guys I really appreciate the feedback. I will definitely get some type of code reader. I was able to isolate this to the RH bank of cylinders. They are all black and show signs of fouling, while the LH side is clean/normal looking. I will do an inspection of the MAF and actuator wiring tonight. My understanding from reading is that the left MAF controls the RH bank of cylinders? Is it normal to have codes without having a engine light?
