Update:
Drove city and hwy after cleaning MAF and tightening up coupler bands.
Car fired noticeably quicker. Throttle response and acceleration noticeably better. RPMs didn't pop up and down, but it hasn't been doing it all the time so I'll keep an eye on it. I started out with the AC off. Drove about 3/4 of my drive with it off. Then at a stop light turned it on. When I turned on the AC the RPM fluttered for a bit then seemed to settle out before I came to the next stop. Didn't see much fluctuation after that though so maybe it was just adjusting to the cleaner MAF when load came on it. Although the AC seems to be straining it...I don't know, maybe I'm making it up in my head.
Cleaning the MAF certainly made a difference. I had no idea filter oil would affect it that much and that fast. Is there a dry cone filter?
So I filled up the tank and will see what happens. Keeping an eye on it bogging down.
BTW - MPG for my last 4 tanks including this last one:
6/29 - 18.6 city
7/1 - 26.5 hwy (I think I oiled the filter right before this trip)
7/15 - 17.5 city
7/25 - 16.3 city
