It runs really rough the whole time the light is blinking. Then, the light goes away, and it runs normal again. I bought my truck in Dec of 2007 with 32,000 miles, it now has 92,000 and I have not be able to afford any of the maintenance due to loosing my job a while ago. So, is there any ideas what's going on? If I take it to a place with a code reader, and the light is not on, will it still say whats wrong? This is the newest vehicle Ive owned, and I dont understand the computer stuff!

I've noticed the exact same thing in my f150. I would accelerate hard to pass someone, and I would get that violent shutter and blinking CEL. I thought I would have to replace my transmission for the longest time but holy cow am I happy I found this forum! My 2010 f-150 5.4 has 176,000 miles on it with the original plugs. I'm gonna get them changed in a heartbeat! I just hope I didn't damage the cats driving it like this for about 5,000 miles. Love the truck otherwise! The shifting is just as smooth as the day I bought it 👍.
