First off let me start with, My problem started after I installed my 75 MM TB and Ported Intake plenum.. (Stock plenum ported bought off ebay) About 2 days later i got a check engine light. But my car was scheduled to go into the shop for the supercharger. So they cleared codes and tuned car with the charger. A day later they came back.. So i put new 02 sensors in front (rear is turned off). SOO anyway here as what im getting...
