It's early on a Sunday morning and I'm trying to figure out my engine problem.
Here's what happened.. (2005 4L)
We had a really hot day (100°F)
I was really low on gas.
My gas cap was defective (loose) but everything ran fine.
The next day I noticed that my "check engine" light was on and my engine ran really rough when moving. I filled the tank and bought a new gas cap. I've started the engine a few time but it's really rough... any ideas?
