Hey All,
I have done the following to my car: Changed the oil, new plugs, new coils, changed the rear differential oil, full tranny fluid/flush, pressure regulator spring, and yelled at it.

I still have the problem of the car not shifting into 4th from 3rd correctly. Now today, it got stuck in 3rd and wouldn't even down shift. The supercharger is making a screaming noise threw what sounds like a blow off valve. The car threw the following codes: P0806 AND P0410. I have no job so I don't really have the option of taking it into the dealership. I was just wondering if anyone had any insight I could try because its beyond my knowledge now :(

Thanks In Advance!

Derek Abbring

Thanks, any idea what that translates to as far as what I should be fixing?

Secondary air system, check the shut off valve and the check valve they tend to get gummed up with carbon. There are some threads here on how to replace both.
