I finally took the time to replace the $50 EGS solenoid in hopes of fixing the insufficient flow for the secondary air pump system. It's been a week now, and still no CEL!

Last thing is to replace my A/C compressor, think DIY or pay.

Question about the serpentine belt for those who have replaced it, can you get at the tension bolt from below without putting the car in service position? I'd like to just swap the a/c compressor from below without a major PITA job.
