Unplug the maf, see if it improves, if it does, clean the heating element in the face of the maf.

Cleaned it and tried a different one. No change. manifolds get red hot and converters are not plugged.

Unplug the upstream O2 sensors and see what happens.

Have been lurking for a few year now but this ones got me. We have 4 top notch techs and all have taken a stab at this one. Any one ever seen a chain jump with only 60,000 rounds.

I guess we should have asked, are you sure the timing isn't retarded?

I would recommend starting with checking the basics first. Is cam timing good? Unplug the cam sensor. You said the cats weren't plugged, did you drop the pipes to verify? Install a back pressure gauge? Is the fuel fresh, or has it been sitting awhile? Does the fuel pressure drop under load? Will the spark jump a good half inch? Is the spark blue? What is the compression? Engine vacuum, at idle, and 2000 rpm?

As far as seeing the chain jump, I haven't seen it happen before, or heard of it on a 3.8, but that doesn't mean it can't!

Yes, is the check engine light on? Have any codes been found? Have you pulled the plugs?

How many miles on the engine? I agree a chain jumping is very rare if ever!

Edit:

Just saw this. If the exhaust manifolds are glowing red, I would say chances are the cats are plugged like said.

Runs no different with exhaust dropped. Converters are not plugged. All data on modis looks good.Compresion, all have 150.

Have you checked for crossed plug wires? No lean codes?

Did the customer bring this in like this or did it start after a repair. Any prior/recent repairs done?

Are there any after market mods? injectors, power chip, K&N air filter, ect? Is the fuel fresh? If that all looks good, possible a bad pcm? If you have 150 compression on all cyl, I wouldn't think base timing is off. BUT, Ford pcm's are NOT common to go bad! Is the EGR stuck open?

Ha, finnaly fixed it! I really felt it was retarded ignition, found the balancer key had sheared off and moved about a 1/2". Runs like a top. Thanks for all the replys.

I have seen that happen, but I wasn't thinking of that either.

    • The new ones don't stay in place very well either. I don't think you would want to put your weight on one either but they work for what they are. Now I kind of seem to remember seeing them at their shop, one the reasons they were redoing them was because enough air didn't go thru them too well.  I think a product right between these two designs would be perfect.Thanks for the reply, 
    • If this happens I will move to Canada but not for the healthcare, just the fishing. Any more bailouts and I riot, we all should, I don't care what they are for.
    • Nah, you and your glorious leader have already shown that you are intimidated by men in tights.
    • Well despite our so so play that last couple of weeks we are still doing pretty well. Really wish we could have closed out that game against Vancouver this road trip but its a long season and we will win/lose games that should have gone the other way many times. Wild are currently sitting 6th in the conference, we have the best goal differential in the west (+16) and 4 games in hand on the two teams behind us. Read somewhere our advanced stats are good too. Dubs is playing amazing, our D is alwasy solid. Scoring is still somewhat of a issue but we are sitting middle of the pack in the NHL so as long as the D holds we should be ok.
    • Those are the 1st gen covers. They done stay in place, at all. Definitely not child or dog proof. I bought the new honeycomb version at the show and they seem way better. 
    • Start one? Bahahahahahaha!
    • Well the teriyaki sticks are very good, I made them to Curlys recipe but with powdered milk (RH1) and more water to compensate. Then I made the pepper sticks but instead of water I used Grainbelt Nordeast, close to three bottles for a ten pound batch. I also added powdered milk, minced garlic from a jar and mustard seed.  What a great flavor! These mixes are proving to be tasty.    I'm smoking 3 loins of canadian bacon on Saturday.    Come on ice!
    • You guys need to start an HSO drama club..    
    • Just hold the bottom of the ducer to your ear with the unit on and if you hear it clicking it's good. If not it's junk.
    • Where did you get those heavy duty hole cover with the holes in them? I just checked their site and don't see them. I might have to stop over at their office today.
