2006 Explorer - Timing Chain Question

[Kirka]

Its torn down and waiting on the owner to get the parts.

On your #3 miss, try swapping plugs and/or wires to see if it follows it. You think the intake gasket might have gotten pinched or something? check engine light or any code?

Try swapping the injector with a different cylinder and see if it follows it.

Good luck, let us know what you find out. I might have the same problem.

Yeah, I tried swapping wires between 3 and 2, no change, swapped plugs between 1 and 2, no change. Since it is a wasted spark system and 2 and 6 fire at the same times I also swapped them and no change. intermittent P0302 every time, not stored but pending. I did have a time getting the plug back into 2 so I hope I didn't cross thread anything. Might pull the inner fender so I can have a closer look and run a thread chaser down the hole just to clean things up. Next is a compression test, and go from there.

Any more news on your rig? I got mine figured out Wednesday. She is running like a top as of 11pm Wednesday evening.

 

[Kirka]

Afraid not. Maybe they will get the parts and I can finish it out next month.

Good to hear you got it going. What was causing the miss?

Blown Seal on #2 injector. thought I swapped it but when I pulled them for the leak there it was. Didn't oil them properly when I installed them. My guess was it pinched and popped. Had a river of gasoline in the bottom of the valley when I finally figured it out. I haven't checked the compression on 2, but there is no more tick so I'm thinking the seafoam also freed up whatever was slowing down that lifter.
