In addition to Berryman's B-12 Carb Cleaner to clean the TB, I got the Berryman's B-12 Total Combustion System Clean-up pictured in the link in my previous post. Check out
Berryman's website for more info on their products.
The Total Combustion Cleaner is used by unhooking the brake booster line from the manifold. The system comes with tubing that runs from the can and plugs into the hole left from removing the brake booster cable. Start the car and the chemical is sucked through the tubing into the car. run for 8-10 minutes.
After the car cooled (car off obviously), I took off the TB and used the carb cleaner to clean the spray/clean the TB.
When I started it back up, the exhaust was white and smelled like detergent for quite awhile.
