{black}:excitement: So I have a 2009 Cadillac Escalade ESV. It is shooting out a code of P0305. I have installed all new spark plugs, spark plug wires and I’ve even changed the coil. I cleaned out my fuel system with lacquer thinner. I have sprayed around the manifold with WD-40 and car seems to idle fine without turning off. We also tested All cylinders with pressure and they are all at 150 to 152. I can’t figure out why it’s misfiring. Can you help? Thank you
What is the mileage?
