Engine Stutter(oil on plugs) Options

[midtownkc]

I was driving my celica yesterday and it started stuttering going down the highway. I checked the distributor and rotor..both were in terrible condition so i replaced them. That did not work so i went on to check the plugs... the 1 and 4 cylinder plugs had oil on them. I replaced the tube seals and bought new plugs. The car ran fine for about and hour and then started stuttering again. At low rpms the stutter is hardly noticeable. But as I accelerate or cruise down the highway I can easily tell it's stuttering. I'm trying to keep myself from taking it to the toyota dealership and dropping a ton of money on it that way. Any ideas?


thanks
