Why do I get black smoke from my engine?

Because, GM V8 engines are very prone to a rough idle and engine misfire when cold. The check engine light may also come on, with codes P0300, P0171 and PO174. But, as the engine warms up, the engine misfire or rough idle tends to go away; which seems confusing.

What causes a Chevy 6.0 Vortec engine failure?

1. Throttle body sensor failure – Chevy 6.0 The throttle position sensor (TPS) is located on the throttle body and is responsible for controlling air flow into the engine. The TPS sensor monitors how open the throttle is (ie. how much air is entering the engine) and relays the information back to the ECU.
