My check engine light came on and the truck started running like crap. Took it to Autozone. The codes said that all six cylinders were misfiring at one time or another. What would cause all six cylinders to misfire?

Sounds like you may have the infamous Timing Belt issue. Be prepared for a $5000 bill. Join the club!

This engine has a timing chain. It sounds like the spark plugs are worn out and causing problems for every cylinder.

Here is a guide that will help you get the problem fixed.
