One of the codes that showed up was shorted eval solenoid. $210. When I questioned their quoted 2 HOURS service reapir time, I asked him what justified 2 hours to replace a $20 (dealer price to boot) eval solenoid... " I think they've got to drop the tank or something"
The result for my $92 "diagnostic fee"? A poor photocopy of a han dwritten note from a technician, showing a few trouble codes. When I asked about getting a printout of the diagnostics, the service guy says "that's all we got. the tech just put in the system "customer declined service"". What a rip!
