Missing, low power, Idles rough, Check engine light on.
Check engine light came on last night and at exactly the same moment truck started running and lost most of its power. This lasted a few seconds and then ran normally for a few minutes.
Problem began to repeat itself. I shut the truck off and it restarted fine, I was able to rev the engine in nuetral and proceed for a few miles. Then it happened again. Everytime the check engine light instantly corosponded to the poor running. When it did this I was only able to achieve 50 mph after a couple of miles.
If I restart the truck there is no check engine light for 1-2 seconds and the engine runs great. after a couple seconds the engine light comes on and the engine instantly starts running rough.
Oil is new.
I would suspect fuel by the way it runs, but it idles/runs perfectly until the check engine light comes on.
I am very mechanical and have all tools for most repairs.
I am going to have the codes pulled at local dealer if needed, just hoping this is an easy fix and that won't be needed.
This is my first post on here so please take it easy on me if this problem is common knowledge.
Thanks for your help.
