PO174, P0306, P0351 Check engine light on
I have a 2005 F-150 V-6. I replaced the coil pack about 6 months ago and just had the plugs and wires replaced about 2 months ago. Today the check engine light came on with the following codes:
1) PO174 --- Bank 2 System To Lean
2) PO306 --- Cylinder 6 Misfire
3) Po351 --- Ignition Coil A Circuit Malfunction
Does this sounds like a vacuum leak?
