I posted here three weeks ago about cleaning my throttle body and then my RPM's being way too high and my service engine light going on. I picked my car up yesterday and when I started it the RPMs were hight but thats because the engine was cold. Well I drove it home put it in park and to my surprise the RPMs were at about 1,100 (I guess its better than before 1,400). I take the car back today and after they check it they tell me that I need a new computer. I was like WTF the car only has 29,000 miles on it never had any problems, I clean the throttle body once and it already all F*cked up. I talked to my friend who is a mechanic at Schaumburg Nissan and he said that our cars are very sensitive and this happens all the time. Our throttle bodies are electronically controlled so if try to clean it in some cases you will get away with it in others you will get problems that will cost you a lot of money. Thank God that my car is still under warranty cause I would be screwed right now.
Moral of the story, do not mess with the throttle body or you migh have to cough up some mad $.

 

So how do you clean the throttle body on an 02+ max?
