I experimented today. I got out my heat gun, turned the car on, and did some throttle testing. As expected all was well. Then while the car was on, I heated the Bank 1 Servo to 100*C, and turned the ECU off and back on. And Bank 1 generated a tracking fault!
I tried to do the same with Bank 2, but it wouldn't fail even at 120*C. I had a spare servo, so I installed it on Bank 1 and tried without success to recreate the problem. Perhaps the whole deal was a bad servo, or at least a heat intolerant servo.
More to come: I'm on track this weekend, and we'll see how it goes.
