If you have a misfire in your 2004 Mazda Tribute, you may notice the engine lag when you try to accelerate, and it may seem smoother while driving at a higher pace. This is a clear indication that something went wrong. You can use your certified OBDII scanner to understand why it's going on if you have a check engine light. Misfire codes for 2004 are from P0301 (cylinder 1 detected misfire) to P0306 Tribute codes (Cylinder 6 misfire detected). You can replace the problematic ignition coils to a different cylinder and scan if the misfire is following the inflammatory spirals if you want to be sure the ignition spindle are functioning before buying new parts. You will be sure to know this before you waste your Mazda on money. After changing the ignition coil, we suggest driving a little while to let the computer read the new misfire location and register it, otherwise you may find an incorrect result.
