Rower

So years ago I came up with the idea of fixing the A/C clutch gap problem with clips from bread bags and Krazy Glue. I did a write up w/pics and still get PMs thanking me. A couple days ago, the ETM on my moms S60 died (I think). As I read here on the forum I started understanding how these things fail and got excited because I thought I had another fix for the forum, albeit temporarily. Armed with a camera, I took pictures along the way because I hoped it would work.

Basically, I shifted the location of the brushes 7mm to the side so they would rub on the side of the strips that had not been worn down. No dice. It didn't change anything. My suspicion is that I didn't fully understand how the strips worked. I thought that the brushes were no longer making contact with the carbon (or whatever the black stuff is) because it was worn down to the plastic. So if I slid the brushes over a bit so they made contact with more of the fresh carbon, it would solve the problem. Now I think that because so much of the carbon has been rubbed off, the resistance (of area of the carbon) has changed altogether and its just totally out of range. Can anyone confirm this?

Its a 2001 S60 non-turbo w/137k.
Codes as follows.
P1620 (TPS Sensor) Injection Pump
P0507 Idle Air Control
P0420 Catalyst system
P0442 Evap emission leak.

Idles very rough.
Won't go passed 2500rpms.
The engine sounds normal as soon as you give it gas, just wont accelerate.
Won't go passed about 20mph.


In one attempt, I wedged the throttle open about half a centimeter and then the car would rev up like normal but as soon as I tried to drive it, the brake booster seemed to stop working. I didn't leave the driveway.
