Brucon is lucky cause he has an engine light and error code that came on and its easy to go to Ford and say fix it. I feel sorry for us guys who never had an engine light go off, yet there is an intermittent problem that they can never seem to fix.

If its an igniton related miss the cylinder would be rich due to fuel not being burnt but if its an injector or manifold gasket leak the cylinder will be lean due to either no/minimal fuel injection, or excessive/unmetered air intake into the cylinder. Just by plugging ids in theres no way they can tell

Hate to correct you as most your info is great but...............

any missfire will show as lean if reading from an o2 sensor, different though if reading from a 4 or 5 gas analyzer :)

Oh yeah I was just talking real world as in whats actually happening in the cylinder, theres still no way they can tell if an individual cylinder is slightly lean using ids

Would loose turbo manifild bolts give rise to a lean code?

Had the engine light come on my BF once, and was told the code was related to a lean condition.

Apparently Ford said loose turbo bolts was the cause of the lean condition.

yes it could cause a lean condition to be reported without the car actually being lean, the car would actually be running rich
