you would be supprised about how many "technicians" don't know info like that, as a lot of the time they don't really care if it doesn't involve fixing the vehicle, in my experience, dealerships are nowhere near the best place to get your car serviced, unless it is under warranty or you /your mechanic don't have the proper diagnostic equipment

 which is why my gt will never set foot on a dealers property, unless she'd doa and under warranty......or being traded in on a boss or shelby..

If you're replacing the ecu, you will surely need to know it since non-sequential mode cars have injector wires combined meaning they are not interchangable.

it was plugged EGR ports. this engine has a single egr port in the intake runner for each cylinder. when you remove the upper plenum, it looks like there's fuel injectors sticking out, pointing up.
 what had happened, was that all ports 'cept #1 were plugged. by them plugging up, now all the recirculated gases are being fed to only 1 cylinder, effectively putting out the fire in there.
 when the ford tech got the van, he simply ran the cylinder power balance test through the scanner. he'd never taken the time to run a physical compression test on that, or any other cylinder. by skipping that single step, he screwed himself. when i saw the report that they gave the customer, i duplicated the problem, scanned for codes, then compression checked that cylinder, and only one other to verify good compression....#1 was around 150 cranking. after that, i just started looking for sources thart could kill a known good cylinder, and found the egr to be the culprit.

 i gotta say, the dude was happy to not have to buy a new van or engine....

 

I was thinking coil pack since they are very common, the clogged ports show up when driving causing the concern when the egr opens up, must have missed that part.
