Just another thought, when I was having my problems and the check engine light was on I was only getting 12.9 volts at the control module insted of 14.1. If the system is only getting 12.9 v instead of 14.1 that could have some negative effects.

This is what codes I got when it happened.

It looks like you are describing the voltage from the alternator when charging the battery (14.1v) and 12.9v is when the battery has near full charge.

Don't know from where you are taking these measurements, but low voltage digital electronics (for the most part) run at 5v, 12v, 15v and 24v and these can be positive or negative voltage. Since the truck is a 12v system all your inputs should be of 12v (+-) and then regulated up or down on the board or an outside regulator power supply. So 12.9v should be more than adequate.

Ok, I have never seen it do this before. Also while this was going on the cats were running 1500 to 1600 deg. This was all going on after #4, 5, 6 missfire during a rain storm. Just wondering if it was a product of the missfire. I was running torque at the time of the missfire.

When mine did it, I only had the p0300 code. CoreyMS said he had it once and only once. So I have high hopes that's all mine will have.

Let us know how the dealership helps or doesn't.

Not following you. Statistic in this case is number of faults/truck sold. Even 1000 of 400000 is statistically insignificant - unless you are happy with an extremely low level of confidence.

You are arguing principle and I have no desire to take up that argument. Ford is aware and is also looking for a reasonable fix.

I am pointing out there are options for solutions. Thankfully, people have taken the time to experiment for a fix and through testing appear to have a viable alternative that will allow incessant biotching on a web forum to end and enjoying a monster of an engine to begin (or reboot, perhaps?) BTW - I disagree that a 1mm hole in the IC will render the warranty invalid. I do not think a tech would even see it.

My 2011 seems to do it on a regular basis if I punch it. Usually after it does it one time it will go away.

Hi rockhead11 and Shan.

Have you taken your truck to a dealer for diagnosis? That is going to be the best first step in getting this concern addressed. In the meantime, send me a PM with your name, phone number, VIN, mileage, and dealer info, and I'll take a look for you.

Ashley,
I took my truck in and the parts have been ordered but I'm not sure Ford is taking the correct steps, by making the cac less efficient, to solve the problem. I have purchased new sparkplugs and coil tips and installed them. My truck currently runs better than it ever has. I am leaving today to head to Destin Fl and I am taking my truck. I will let you know how it runs.

P.s. does seem like the gas mileage is down though.

Day 1: So far so good. Been threw rain and getting about 17mpg with a average speed of 70.4 over a 6 1/2hr period.
