    Those don't look right. I assume you've read the sticky on pulling DTCs? Pull them yourself, and use the link provided for definitions.

    Re: Trouble codes

    Those will be 4-character OBD-1 codes - a capital letter followed by 3 digits.

    Re: Trouble codes

    No need to replace the expensive EGR valve. Just give it a good cleaning. Pretty sure there is a tutorial in the Tech Tips section. All it should cost is some time and a can of TB or carb cleaner.

    Timing is not urgent.
