Today getting on the freeway the truck started missing badly and shaking. The CEL came on so I kept going to the offramp. It missed badly over the entire way home, and was pinging horribly.

This comes only days after my plug change / tune up.

Input at this point would be much appreciated.

You may have a bad coil on plug connection. They have had some problems with that plug on coil. I think it will throw a code like P 035 and then 1, 2, 3, etc. Have that checked out.

 

The COPs need to be checked out. Makes you wonder if they messed one up.

 

Will update

 

Fixed. Loose COP on #1

 

Good Grief! I'm so good it scares me! Glad that's all it was.
