Re: servo motor/egcv problem/question
No way for debris to get in the servo motor that is a sealed unit. And I dont know how it could happen, but it did to me. I had a small pebble under the cover that covers the exterior of the valve assembly it jammed the valve and caused the gears on my servo to strip. I bought my servo new from a dealership. If you troll e-bay you may or may not get a good working servo. If it's not good then your still gonna have to spend the bucks to get a good one. As for pinning the valve wide open I will have to defer that one to others on the board. To my knowledge the only way for the error light on the FI to be cleared is to install an operational servo motor.
