Need help w/ electrical & CEL troubleshooting
My car: 05 OBS wagon, Auto, 74k miles. Struts, springs & catback. No engine/intake mods.
Here's my symptoms:
CEL flashes at all times
When ignition is in ON position w/o motor running, I can hear various relays clicking on & off. (the 3 large ones in the eng. compartment relay box, and another from the passenger side rear of motor).
Car seems to idle lower & almost stall, less power going to P/S pump at idle. Drives great at speed.
What I checked:
I ran the Codes & came up with:
P0137
P0502
P0503
P0851
P1152
P1153
P1518
P1153
I had the battery tested and it's @ 13.5v and 450 (iirc) CCA
The stereo was stolen from the car (stereo only, no wires looked cut), then I replaced the unit. About 8 days later these problems started. NO other problems with the car until now.
Any suggestions?
(if this should be posted under Technical Forums, let me know. There's just a lot more ppl here it seems

Just today, I had the stereo shop check everything out. They said all connections were good & disabled the alarm etc... to troubleshoot.
They said everything looked good. Are there wires behind the stereo that I can inspect w/o removing the deck?

BTW Matt, on the suspension end, the car handles GREAT! The front settled down a bit more & looks nice. The alignment guys said it's at 0deg Camber atm, so I'm going to hammer in those bolts so I can get it to -05 or so. Thanks for all your help!
