So I recently had a lot go wrong to my engine at once, but after doing some repairs I seem to have fixed all the issues but now cylinder 3 does not work. I just replaced the distributor, plugs, wires, and timing belt, and now get code P1399 (misfiring). I narrowed that down to cylinder 3 which is getting no ignition, and I believe that it is causing gas to come out of my exaust. Any recommendations on what I should do would be great!
