Okay, got a couple more things to add and maybe some of you smart ones out there can help. First off, I wanted to say that the idle surge condition is much more common now. To be honest, it might even be more common than high idle condition I described before. It's a fast surge, too. I timed the surge for a minute and it surged up and down 72 times. Yes... seventy-two. One thing, though: I did over- and under-estimate the surge rpm. It surges between about 1100 rpm on the low side and 1600 rpm on the high side. So, it does drop some from the 2500 rpm that it has when the idle is high, but it doesn't get as low as it's supposed to be when it's jumping up and down.

One more very important development has come to light. The check engine light now comes on. And, usually, it stays on. I went and bought a LED and hooked it up to the diagnostic plug across the 1 and 12 pins. When the LED started firing, it gave me the same code over and over and over. The code in question was a 43. I looked into that code, and what I found was that it was "EGR (California Models only)". Is that what everyone else has? If so, I didn't know that my car had California emissions.

Anyway, allow me to apologize in advance for my ignorance, but would a bad EGR explain the funky idle conditions that I've been describing? I've never had to deal with a bad one, so I'm not really sure what the symptoms would be. For that matter, could that even explain my turbo problems? Let me know if you guys have got any input on this.

Thanks for your time... again!!
