PO301 Cylinder 1 misfire
PO174 Too lean
PO171 Too lean

Those were the codes they checked. These guys (O'Reilly's) aren't trying to sell me anything. I've talked to them in the past, and they know I only get OEM parts. I was just dropping off the fan clutch tool kit, and had them check the codes.

I'm going to change the 1, 2, and 3 cylinder fuel injectors, reset the codes and restart. If that doesn't work, I'm taking it to Ford to have a professional diagnosis done.

Any other ideas are greatly appreciated, though. Keep 'em coming.
