My car idles high when stopped or in park. I went to Autozone and they ran a diagnostic. It came up with codes P0300, P0301, and P0401. I replaced the ignition coil, but the symptoms have not changed. I was going to try to clean the EGR valve, but I am not sure where it is located. Where would I find the EGR valve and how can I get to it?

you will need to remove the air intake hose and top portion of the air box. its a tight fit but easy enough to access. you will need a stubby 1/4" ratchet with a shallow 12mm socket to remove the egr bolts.
