Have a 2000 Taurus, FFV 3.0 12V engine. 90,000mi. I has just now started to idle rough after start up with at least an 8 hr. cool down time. Engine light came on, had it checked, shows misfire, #2. Any ideas what I may be looking at here, like injector, wire, plug... Had plugs and wires changed at 50-55K mi. I put in two bottles of Chevron gas treatment, to see if it may be an injector that was carboned up... After car runs for about 3 minutes, smooths out...Any ideas would be appreciated.. Not time yet for a fuel filter, but do not believe this is what is causing this. Thought maybe water in gas, but car gets better after warmed up ? Thanks in advance...

Remove IAC and clean it and the passages behind it. Sounds like the valve is sticking.

Check coil.

While you're cleaning IAC valve, take out accordion hose that goes to the throttle body and check for carbon there. Might be good idea to give it a clean.

Check coil.

I agree.
