Cold Start Issues
A few morning back in the summer I noticed when I would start my truck, it would have grumbling idle. It would take a few REVS to clear it out and i went on my way.
We had our first 50* morning and when i went to start it up...
I turned the key and nothing.
I had to hold the key on for about 20 seconds and finally it caught.
It then ran rough for about 30 seconds and then was fine.
