service engine soon light on after changing UDP

[sabrooks]

Mu service engine soom light came on after changing my pulleys. I am using the Steeda pulleys. Anyone ever have this problem. I took it to a Mustang performance shop and he said sometimes the AC pulley can trigger it because of the new pulleys. He reset it so I am hoping that it does not come on again.

The light came on because the balancer was not torqued properly..

The computer is seeing a misfire code..

Retorque the balancer to the proper ford specs and it will be fine..
