Well.. umm.. when your engine is running their is oil being squirted onto the valve train.
Since your engine is running and the cams are moving then it is likely oil is going to get splashed out of the oil cap if it is off.
Also.. correct me if I'm wrong.. but I believe your engine will idle bad if you remove the oil cap while it is running because you are essentially creating a vacuum leak.Comment

:stupid: Oil is supposed to be moving around, and if it's hot I suppose it could be thin enough to look like it's splashing or spitting around. If you take the oil filler cap off while running you ARE letting unmetered air into the system, thus in effect creating a vaccuum leak.

That sputtering is likely a misfire. Have you checked yoru plugs and coil pack boots?
My 92 E36 had that same problem. Turned out one of the coil pack boots was completely fried. Is your car throwing any CELs?Comment
