Cleaned my IACV and throttle body. It runs much smoother. I've been trying to find out why I'm getting 13mpg and thought this could help. After seeing other people's corroded IACV's I thought it was worth checking out, but I don't think mine was that bad by comparison. Before pic (sorry I didn't take an after but it was much better)
Here's a question though. I found motor oil inside my plenum right after the TB. I had a bad pcv valve that I replaced in august. Could this be left overs or do I have another problem. I checked the new valve and it still seems good.
