Hey guys, long time lurker, first time poster.
I changed out my upper torque mount yesterday and the car started throwing a ton of codes. I don't think I knocked anything out of whack but that's obviously not the case.
I'm getting P0446 (EVAP), P0505 (Air Control), P0135 (02), P0141 (o2 heater), P0443 (evap control) and P1671 (manufacture control)
So... That's a lot of things to go bad all at once, so instead of trying to trouble shoot them individually, I was thinking it's something upstream from the emissions gear. I just don't have any idea where to start. Ground fault? Any thoughts? Thanks very much in advance.

Changed the upper torque mount... now, oh so many codes...

Those are probably not something you could have caused, unless you were climbing all over the engine with a blindfold when you were changing that mount.
Reset, see what comes back. Take a look through your vacuum and boost hoses, and check that your charcoal canister didn't fall off and that the hoses are connected. Check if the evap valve stays shut w/o 12V. It could be that your cam position sensor is going... but reset first, and see what comes back.

thanks for getting back to me. I did reset and they ALL come back. It's a NA car so no boost hoses but i glanced at everything else and it seemed ok. There was a hose that had been bumped off underneath the airbox but i put it back on... nothing. Another note, Idle gets notably rougher when AC is put on.Sommerfeldt wrote:Those are probably not something you could have caused, unless you were climbing all over the engine with a blindfold when you were changing that mount.

I would start by checking very carefully the wiring and connections to the oxygen sensors. A problem there could explain several of these codes. That wiring is down below the brake booster., near the firewall on the air cleaner side.

It's really easy to,pinch the wire harness on the upper mount and cause a zillion codes.
