[QUOTE=REDFIRE_GT_BEAST;6613363]Um cwf340 yea the CAI does i seen it with my own eyes the CAI was worped from heat of engine so we took it out put new one in and the check engine light went off so yea i think CAI can unless you have some other reasoning.[/QUOTE
I dont think you understand, yes a warped/leaking CAI can cause a CEL. but not a misfire code. a CAI would most likely set a lean code p0171,p0174. totally differant codes from a misfire code.

Don't argue. cwf340 is right on this one.

I dont think they have.. They said they could take out each individual coil and stree test it but the dealer said he would take care of it, said he checked and everything was fine.. He ended up bringing it back to Ford although and they still couldnt figture out whats causing it.. My service engine light was blinking for about 5 mins earlier today then just went back to being solid/on. If you turn the service light off it stays off sometimes for about an hour then back on
If the car feels like it's running fine while all of this is going on, it could be the loop to the PCM is bad. I've heard of it happenign where the there is absolutely nothing wrong with the car but a loose PCM wire causes a code to be thrown. It's rare but it does happen.

a blinking service light is severe misfire as in damage to the engine could occur. You would definitely feel it.
