GM said as long as I can stop and wait for a few minutes, I should be fine. But they suggested I stop using the K&N filter and just use a FRAM or other quality air filter. One of the mechanics I spoke to told me that, while they will fix a car that has a K&N air filter in it, they will cause problems, and absolutely hate them. If you fix your own car, pretty much, do whatever you want, but he wished that K&N and other oil-based filters would void warantees.

I didn't feel oil when touching the filter in my case. Don't get me wrong, I don't want to put in an oil-based filter again. I just want to find out what is going on with the oil in my throttle body. There is still a little bit of oil, but not like it was.

They don't filter as well as the paper filters (and once they are clogged up enough to filter as well they don't flow any better) and they mess up the mass. GM's had enough of it.

As for the oil messing up the position sensors, that's kinda weird. I didn't think any of that was exposed in the TB tract. GM actually said that they are or was it a dealer?

More than one dealer has told me that oil getting into the throttle body can cause this problem. Probably causing the trottle to stick or drawing more power to move it, which is probably where the error is comming from. After it's "unstuck" the error code clears.
