Default Misfire

A little over 20k miles ago I was having these same issues.

CEL indicating that both bank 1 and 2 are lean, misfire in cylinder 1, and misfire detected within first 1000 revs. (P0316)

I changed my coil pack out and it fixed the issue. But now 20k later I'm having the same problem. Could the coil pack of failed that quickly? I replaced it with a BWD pack from pepboys.

I have check for vacuum leaks and everything appears fine. I hacked off some of my tailpipe because I bent it on a trail. Not sure if that means anything. Just did radiator flush and has been maintained pretty well for the most part. Also just changed fuel filter.

I'm at 117k now.

Could the cam syncro failing cause these issues?

I don't if my experience helps but since no one else replied I will. You exact situation happened to me but it was on 2002 Sonata 2.4L 4 cyl. Sirius engine. I had a similar problem of misfire with a code as well ( I forget the exact code) Anways, It turned out that every time my coil pack for spark plugs 1 and 2 would get wet or be humid, it would malfunction so I changed it. Not even a year later and approx 20,000 KMs later the smae problem occurred except it was the coil pack to cyl 3-4. So i changed that and problem solved. Its been 4 months and its running great in even the worst conditions. Might or might not help, but it might guide you in some way

The last time this happened I started with the basics. Changed the plugs and wires, air/fuel filter, and none of that helped. It wasn't until I changed the *Ignition coil* when the issue was finally resolved.

I replaced the coil pack and still the same issue. The previous owner removed the air box and put a cone filter on it. I am going to go to the junkyard today or tomorrow and try to find an air box. Maybe thats whats causing it.

I often get 2 codes at once: P0316 and one of P0300 through P0306. There is a Ford Technical Service Bulletin for the problem, and it involves defective heads and a major expense since you're out of warranty. Ford has known about it since at least 2005 (the date of the TSB). The TSB is here: http://ww2.justanswer.com/uploads/jm...sb05-26-03.pdf

If I have the problem described, and I'm pretty sure I do, my valves are being trashed and soon my engine will die. I'm annoyed, since I am the original owner of my 2004 Edge 3.0L and they never told me about the problem while I was still under warranty. I would like to know just how many other victims there are out there, because I think a class-action lawsuit is in order.

By the way, it looks like other models and engines may also have TSBs for the same issue. See one for the Mustang here: http://www.stangnet.com/images/stori...s/06-05-13.pdf
