From elation to broken in 24 hours. Service Engine Soon CEL

[broncoJR]

Check Engine and Engine codes have absolutely nothing to do with the actual engine. These are Smog/Emissions related. If you dropped a valve, you wouldn't get a light, you'd have a blown engine.

Since you didn't actually provide us the code, we can't say what is wrong. But the most likely issue is either a spark plug wire, or the stupid "Coil over plug" that Ford uses which are notorious for going bad.

The messages I got didn’t have a code. Here is what I got back from the service tech, don’t know if these codes are meaningful.

P0306 is cylinder misfire on cylinder 6. (which is what the paperwork says, so I guess you knew that already)
P0301 = cylinder 1 etc

Normally this code is a bad COP (coil over plug), but since this a a brand new vehicle is it most likely that COP or COP boot was not seated correctly. It can also happen if the electrical plug for the fuel injector is loose.

I had 1001 mi cruising at 75 plus in strong headwind on I-40. Suddenly check engine and driveline malfunction warning popped on dash and lost power in heavy traffic …
Stopped, checked all fluids , restart engine and sounds fine .. warning lights still on. I am 100 miles from nowhere Socorro NM ..
long story short .. got to dealer in ALB NM and I had found and they agreed clamp in inlet to mass air from turbo was never tightened so under high boost it had blown it seal and computer went into limp mode..
maybe check your clamps

Fault codes thrown because of the loose clamp under high boost. Tightened clamp Dealer had to do reset to get out of limp mode but at 2600 MI no further issues
