^ I have heard of Canadian tire trying to scam people who don't know better into buying a new engine when its a minor problem, what ended up being the problem with the van cap? plugs?
plugs or plug wires?
Does the part that fixed it start with a "C" lol
Horror shows go both ways sometimes dealers are no better that a bad independent shop. I bet we could share some story's that would make people ditch their car go back to riding horses again 
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....
