Engine rough idle and P0302 code

[routerman]

I have a 2000 Taurus 3.0 DOHC giving P0302 misfire on cyl 2 and idling rough. Pulled plug on cyl 2 and it's got a lot of oil on the threads. Swapped coils on cyl 2 and 4 and plugs as well which is how I saw the oil on 2. No change after coil swap and haven't checked after plug swap but have a bad feeling someones going to tell me I have a head gasket leak with the oil in plug threads...who wants to give me the bad news??? Or maybe it's something not so bad.

Oil on the plug threads is just a sign you need to replace spark plug hole seals. They are included with a cam (valve) cover gasket set or may be able to be purchased separately. Installed from inside the cam cover. Might read the forum misfire sticky, but I'd guess plug/coil should fix your po302. Any other codes, such as po171/174 lean codes?

Yeah I'm a GM guy and an idiot. I swapped coils on wrong cyl to start with and read the misfire doc and realized what I did. Swapped 1 and 2 and code followed so replaced coil and it's fixed. Going to replace plugs as well while I'm at it. Thanks for taking a look and replying and sorry for wasting folks time.

Sounds like a simple mistake-no need to feel stupid. Accidents happen, and you fixed it fast.

Now, as for being a GM guy...

That's not a simple mistake.

Well I considered becoming a Honda guy but after the tranny problems on the Odyssey I can honestly say after 6 years or 100,000 miles they all need work and these forums are a tremendous help for those of us that give it a try to save a few bucs...I grew up on GM's but they've all let me down along the way...lol

Yeah, the General has gotten worse. Gen II Odyssey transmissions are iffy. Although I hear that a lot of older V6 Hondas have transmission issues. Parents have 180k on a 2005 Odyssey, no major mechanical issues other than plugged cats. Granted, it's got the towing package, so it has the tranmission cooler as well, which is supposed to help.
