I was reading previous threads about TPS, CO2 sensors, hal sensor etc.
What is the correct trouble shooting order? Am I on the right track?
Check in the electrical box and see which Coding Plug (or if there isn't one) has been installed. Do you have any add-ons like Techlusion, Powercommander, BoosterPlug, iice air? Do you have a stock muffler?

The problem is either too much fuel or too little air. The guys/gals on this forum can get you there step by step.
