Hi all,

have a neon 96 with the following codes: P0300, P0401, P0403. Anyone have a engine section of the service manual that i can use to troubleshoot and fix these, or can give me a url to look that troubleshooting info up? Your help would be greatly appreciated. Thanx!

P0300 Multiple Cylinder Misfire
P0401 EGR System Failure
P0403 EGR System Failure

You need to change your spark plugs with some stock Champion copper plugs and you need a new EGR valve and transducer.
