Cleaning Throttle Body

Auffenburg just informed me my throttle body was dirty so here is what i did....

The air tube had to be removed from the top of the throttle body.  It is easy to do as it is only held on with a hose clamp.  I loosened the clamp, pulled the vent hose from the side of the air tube (it goes to the valve cover), and then lifted the air tube off of the throttle body.A look down into the throttle body revealed some residue but honestly, it was not as bad as I was expecting.Then I opened the throttle (where the throttle cable connects) and found a lot more of what I was expecting to see.  Nasty!  The directions for this brand of cleaner recommends you run the engine at a high idle and apply short bursts (3~5 seconds) of cleaner to the throttle body.  This stuff caused the engine to bog down so it was necessary to keep a bit of throttle action going so the engine would continue to run.  When I decided that enough was enough, I turned off the engine and opened the throttle again.  It wasn't perfect but it was a lot better than when I had started.  I'll run it for a bit and then give it another cleaning when I do the next engine oil change. 

WOW they wanted to charge me $104.00 for that....
