The engine wiring can degrade because the insulating material falls off leaving the bare wire exposed. This can cause many problems depending on which wires are exposed and what they touch.

Rough idle, engine misfires above 3000 rpm. Inspected wire harness and noted degraded wire insulation causing intermittent shorts throughout the entire harness. Dealer wanted $800 for the harness and 5 hours labor at $130 per hour, I purchased the Mercedes OEM harness through ECS Tuning (www.ecstuning.com) for $608 and installed it in 6 hours. Fired right up and runs smooth as new.
