I was putting a new elbow on the car today and was checking to see if the TB blades were opening all the way. I noticed on the back of the blades there was a build up. The best way to descibe it is it was like semi-dried gray latex paint. It would come off in flakes and liqufy when you rub your fingers together??? The thottle body is about a month old...I put a entire new CAI system on it at that time and oiled the K&N filter really good....no way anything else could have gotten in there. Anyone else expeirence this?
