Issue 1: My A/C compressor had been dead for years. I finally had it repaired last month and now it seems that even the A/C off for an entire tank my fuel economy has gone dropped considerably. I replaced the a/c belt because the old one began squealing horribly upon repair. Since the A/C hasn't worked in such a long time, I don't think I ever changed anything related to it. Should there be something I need to be looking at?
Issue 2: When the cooler weather came around I decided to re-tune the RAF a couple times to hit the lower cells, and I worked on the idle primary/secondary VE also. Didn't touch any other tables. When braking, as I near stopping the idle wants to overshoot and hang around 600RPM before gradually coming up. Tends to occur more frequently as the car is warming up and/or during harder braking. I'll post the current tune and grab a log tonight on my way home.
