I disassembled my intake system today to check for air leaks, as my car has been idling a bit rough. I was surprised to find a good deal of oil coating the inside of the intake plumbing up to at least the throttle body, with oil on the air flow sensor plate and saturating one side of the air filter under the sensor plate. The screen above the plate also had a good deal of oil on it. Can someone give me an idea of what's gone wrong here? TIA.
