Bummer, my VX has 55k on the odometer
After calling St-Charles Isuzu for a quote on the EGR valve, I realized that this part is a common problem among Isuzu vehicles. The sale guy told me that is often backorder. So I believe that there was a real problem with the part.
I picked up the VX yesterday. I have to say that I did feel a difference when I drove it off. It sounds much better now. Before, there was a little metal sound when the engine was shifting. It's hard to describe but it was similar to an old beetle engine sound... just a little.
I tested the VX uphill and kicked down and the check engine light didn't come back. It seems that they did the job right this time.
The only one thing that really annoys me about this whole event is: The service guy strongly recommends flushing the injectors every 20k (for $150). He keeps nagging me with this service but the dealer has no flyers or documentation that mention it on paper! I never heard about this on vehicross.info either.
Thanks!
