Ford Repair Questions? Ask a Mechanic for Answers ASAP
Welcome, I'm Chris (aka Moose), my normal schedule online is around lunch and after dinner past midnight.
I doubt a PCM flash is going to help this.
Will you scan tool run a power balance or cylinder contribution test?
Have you monitored the fuel pressure and fuel trims during this event?
A backfire concern can mean there is a timing or valve issue, can you run a compression test?
This is my 1st answer of what can be many. You the website and myself expect you to have a ~~~5 STAR EXCELLENT~~~ experience with my help. At the top of your screen is the rating box that you only get to use once. Please make sure to complete the mandatory rating when ready or reply and say "I am pleased with my answer". Not rating or rating 1-2 stars does not benefit you nor me in any way.
Keep in touch if there is any way I can help more.
