I bought a used servo on ebay that came off a ZR/ZL and installed it on my 04 F6. The service engine blinked 6 times telling me it was a servo motor failure. It wouldnt move when i throttled up - wide open. I bought it from a pretty reputable parts guy and he said if i send it back and exchange it for another one (all he has is Servos off ZR/ZL) that i will get the same service engine light. I know everything worked when i took the "good" one off the F6 to put on my F1000 so my guess is that i have a bad servo from the ebay guy. The servo motor has no "brains", it is being controlled and told to open from the ecu..?? So, any servo motor off any cat sled should work, right?
