Flashing Check Engine Light
#12
I had the same thing happen I was lucky knew a guy with a obd2 ran it as hard as I could up and down a street by his shop pulled a multiple miss fire code. Changed the plugs cops fuel filter air filter cleaned the throttle body. A few weeks later my cat converter took a crap ford replaced it no charge since it was still under the emissions warranty. Do that and you won't have this problem any more. Also change the fuel pump drive module. Just as a pm thing chances are its going to rust out and die. Read a lot before you do the plug change chances are there o.e plugs. Buy the lisle tool before amazon has the best deal on it and put anti seize on the electrode part of the plug.

What Lisle tool? Have a PN or a link? I have this same problem and am about to change the plugs and wires on my 07 F150 Lariat 4.6L SuperCrew, which I just acquired with 137K on it. I used to be an ASE certified mechanic in the early/mid-90's, so I still got a lot, but these modular Fords were just really coming out. Thanks. Jeff

Im not to sure how to post anything on here but I have and 07 f 150 and it runs rough when at an idle. I hsve a check engine light that comes on and then blinks when I try to give it gas. And when I let go it goes back to solid can anyone explain to me what that could be from. Thanks.

you can also tell you have a bad cat by taking the motor up to operating temp and looking at the cat.. it will be hot and glowing red and smell like rotten eggs.. sulfur smell. A bad cat normally produces a DTC also.

same problem again except it's when I accelerate it will flicker and will sit at 3 grand with no power. Thinking it could be a coil though?
