So i traded my Dodge dakota for a Eddie Bauer edition 1997 Ford Expedition. I replaced one coil and plug(cylinder 4) and it ran fine. now at random times (only in drive) will the AWD lights come on on the gauge cluster and the radio powers down. happens for less then 5 seconds and goes away. also acts like the truck is shutting down? I also hear a clicking noise under the dash when this incident occurs. sometimes when I start the truck I hear a loud buzzing noise under the kick panel on the passenger side. Any ideas? Maybe the PCM is bad?
