A couple weeks ago I was having an issue with my throttle, at any speed, in any gear, if I had my foot just barely on the gas the throttle would just cut out for a couple seconds then come right back. When I pulled my intake off I found that my butterfly valve was completely caked in really sticky oil. What's strange is that I just cleaned my throttle body about 2 months ago and the sticky oil wasn't just caked inside my throttle body but all down the intake all the way to the filter as well. After I sprayed the crap out of it with brake cleaner its been running great until yesterday, I felt the throttle start sticking again. I pulled off my intake again an hour ago and sure enough, there's sticky oil building up on my butterfly valve again.
The only thing I can think of is a bad pcv valve but why its blasting my intake with oil has me befuddled.
So umm, ya... WTF!!!
