Re: engine bogs, no check eng. lite
Even with no check engine light illuminated, it could still have pending diagnostic codes.
You don't mention checking for vacuum leaks, so have you checked for vacuum leaks? -Rod |

Re: engine bogs, no check eng. lite
i checked for vacuum leaks and found none. i noticed smoke coming from back of motor near where i believe pvc valve is located. could my pvc valve be plugged up and if so would it cause my motor to run the way i described it was running?

Re: engine bogs, no check eng. lite
If the PCV valve has a rubber elbow, those have been known to crack on multiple other Ford products and cause a vacuum leak misfire.
