Recently my truck broke down kept making clunking sound when trying to start it. changed the distributor, ignition coil cam shaft, spark plugs and wires.
But any time i go over 70 mph engine light flashes and starts puttering.

Hello, I'm Danny,

Okay, first thing you need to do is access the check engine light code(s). If you don't have access to a code reader/scanner your local auto parts stores have a tool loaner program and can rent you one. Once you check the codes and get back to us with the code numbers we can help properly diagnose your vehicle. I've attached a tutorial showing you what is involved.

Hope this helps and get back to us soon. Thanks for using 2CarPros.
