MY WILL START UP AND THEN STALL OUT.

I replaced the spark plugs and knock sensor and it ran good for a week. Now it won't even make it up a hill. Keeps stalling.

Have the fuel pressure checked. It may be too low.

Is the check engine light on?

Does that mean my fuel pump needs to be replaced?

Those are evap codes. They will not prevent your car from starting.

That's why I am stumped. When it first started acting up I got the code reading for misfiring 3rd cylinder so we replaced the spark plugs and the knock sensor. Was running good for a week then was driving along and it sputtered a little and stalled. I got it started again, revved it up and was able to drive it onto the road where I live. There is a hill on the road and it just kept stalling every time I hit the gas. I got towed to the top of the hill and was able to coast the rest of the way into the driveway. That's why I'm thinking possibly ignition coil.

Check for torn air boot after mass air flow. Or tubes under air cleaner housing.

Believe it or not, it was a loose battery connection. When thye replaced the battery, it was installed incorrectly and never set down all the way. Battery is now on securely and haven't had a problem since.
Thanks to everyone for thier help!
