CEL on, could it be..

The way its acting, thats why I was hoping it was the filter Once we had the code ran, we realized that it was more then that.

We changed the filter anyhow...the gas coming out of it was brown? Not sure thats good LOL And we have a cleaner in the gas. Will be picking up some spark plug wires soon as we can, and just driving limitedly until then. If that doesnt fix it, guess we move on to the injector. Just a BAD time for it to have an issue...

Thanks for your guys help too. If needed, Ill take it back by autozone and have them run it again and make them write down what the code is.

Reset the computer by disconnecting the battery after each fix, and then see if the code comes back.

You can also swap the cyl #4 wire with another cylinder to see if the problem follows the wire. Be sure you move both ends of the wire so you have the correct coil with the correct cylinder. If you need to timing diagram they are available online with a google search.
