Default Adaptive Fuel Limit Reached Lean
I finally was able to start the engine in my Cobra for the first time. The engine appeared to be working perfectly as it started with the first turn of the key. The timing is set at 10 degrees advanced at idle 850-900rpm. I let the engine idle for about 30min. and and took if for a spin around the block and the check engine light came on. I hooked my reader to the ECU and it gave me a error code of 85 which according to the book is a Adaptive fuel Limit Reached Lean. I am not sure what this means or how to correct it any help would be greatly appreciated.
