Hey guys my Mach 1 threw the code P0306 Misfire Detected - Cylinders 1-10.
Fuel pump, fuel filter, fuel rail sensor, spark plugs, air filter have been replaced recently. I even tried fuel injector cleaner.
Time for new coils? Clogged injectors? Car has 80k miles

I found a set of aftermarket brand new coils for very cheap price with lifetime warranty and free shipping. Thought it wouldn't hurt trying them out just to see if the problem will be resolved. $89 shipped isn't bad for 8 coils!

let me know if this works out for you. mine throws PO307 and PO316. i'm lost. replaced everything short of all the coils at once. the car runs strong and the CEL comes and goes as it pleases. almost wish i knew how to disconnect it. my 68 would throw a code everyday if it could, and its doing ok. i hate idiot lights.

well for what its worth i finally got to working on it with some free time over thanksgiving break. narrowed it down to a clogged injector. light remained on for a month, but went away by itself and its been off since middle of december. hope someone can benefit from this.
all i did was unplug injectors and coils to see where a drop in rpm didnt occur and reasoned from there including coil and injector swaps between cylinders.
