cold engine missfire?

So the other day i cranked my stang and let it idle for about 3 mins. While i was pulling out and heading down the road its like a whole bunch of missfires at once but no codes. It honestly sounds like chopping, like a fan blade chopping. Any suggestions?

My wife has an 04 and apparently there's an issue with water getting under the spark plugs. I washed it and it hasn't ran right since

Ive never seen any water in the spark plug wells. But ill take a closer look this weekend. If the engine is warmed up it will only do it if i put it under load but slightly. Im just at a loss

I replaced the fuel filter last week also

Re: cold engine missfire?

i think im just going to have to start from the plugs and work my way around. I just can't figure the cause of this out, sometimes it does it and sometime it doesn't.
