Re: EGR - search this forum for "EGR Bypass" or maybe "606 EGR bypass". It's an easy mod. Legally, the dealer cannot bypass it and has to actually fix it.

As for the intake switchover valve - if the dealer's diagnosis is correct, then yes, you will have to replace it for the check engine to go off.

I've had to deal with both of these issues on my '97.
