Default Rough engine idle or misfire.

Hey all. I have an emergency. My ti is idleing ruff or is misfireing. I thought the problem might be a fouled sparkplug or a loose coil connection. Well when I went to change the sparkplug on the cylinder closest to the grill and when i pulled the sparkplug wire out there was oil in the shaft. I was shocked because I've never seen that before. So I moved to the second cylinder and the same thing except less oil. The last two sparkplug wire shafts were normal. So I cleaned out the shafts and replaced the plugs. I ran the car and checked for any oil leaking but there was none. So now I'm really confused and think there might be a crack in the head or a busted seal. Also when I checked the sparkplugs there was quite a bit of carbon on them. So now I dont know what to do besides taking it to a shop and paying a boat load of money. If anyone can help with any of this long thread, I would appreciate it very much.

I don't know if you have fixed your problem yet or not, but this is what *I* would do to my car:

If my spark plugs and wires had more than 30K miles on them, I'd change them. Then I'd run SEA FOAM or Berryman's Chemtool through it to clean out any carbon, then change the oil and filter and check/replace the air filter and maybe even the fuel filter if it had been a while.

The oil on the spark plugs you mentioned could just be the valve cover gasket has a leak and shouldn't be too difficult to fix if you can do minor stuff yourself.

If that didn't fix the problem, I'd take it to a good mechanic.
