Possible DIY solution to vaporizer carbon blocking is to drill and tap into the end of the vaporizer and plug with a 4mm stainless hex head bolt, as per Meguinnes on Talkford.

It's hard to DIY if you're working though. You need expensive tools, and the technology has changed. Ford's information policy doesnt help either.

I'm retired so time is not an issue, and have spent lots on tools. Problem is Ford's unethical attempt to profit.
Information which might help the consumer with mechanical problems such as you are experiencing, is withheld in the hope of earning money. They try to profit by monopolising the service of Ford cars, pathetic really. Are they really that desperate?
