Hey, Just thought I'd visit the old forum, and saw your post. You have my van, Twinkie! Excessive dust in the intake area was a poor design, I changed the air filter every oil change and cleaned it out almost weekly when it was dry and dusty here in Michigan. Please keep me posted on your progress. I'm *so* sorry about your luck. If you need anything feel free to call...517 851 2466. -Andy
