I recently came across this thread- http://www.custommagnums.com/forums/...all-cmers.html which gave me the motivation to go take care of this on my car. I didn't see any write ups on it so here we go... It's also on my site at Throttle Body
27 thousand miles- time to clean the Throttle Body.
27 thousand miles- time to clean the Throttle Body.
Remove the mass air sensor from the air intake. This is done by pushing back the orange lock tab then pressing down on the black tab as shown. You will also have to do this to remove the plug from the throttle body.
Lets start be removing the air intake, then removing the four bolts with a 10mm wrench. The two bolts on the right also have two nuts that attach the brace that keeps the TB in place with the air intake on.
Now lets get to the two bolts that bolt the brace to the motor block. They are 15mm bolts and it's a tight fit. Also remove the two bolts on the right of the throttle body.
Once it is off, remove the TB.
With your favorite TB cleaner from your favorite local auto parts store, spray it liberally with spray and clean it. Open the valve with your fingers and spray, then let it soak and wipe it out with a rag. Also, spray a rag and reach inside the manifold as far as you can to try to clean up inside it.
Also, when you spray and clean, please take care not to get the spray inside any of the electrical connections inside the TB. Point the TB away from the electrical part to prevent any cleaner from getting inside.

Before Picture (not too dirty at all, really...)
After Picture:
Installation is reverse from disassembly.
Now hook it all up but leave your air intake off. Get someone to help you and rev it up to 2000RPM or so, and have them try to keep it there. Take your TB cleaner spray and spray it into the intake in short bursts and try not to stall. Use as much of the spray as you can. And don't get the spray on any electrical or paint.
