has anyone one done it?
if so how can i?
i was putting stock intake in it and saw black stuff..should i clean it?

 

Well...
I try that on my 5th generation. Guess what happend. End up spending $1200 in repair. well i sray the whole throttle body with cleaner and used a toothbrush to rub is off (to makesure i didn't scratch the plates) and used a cloth to wipe it off. What happend was after i put everything back, the ideal rpm went up, car start to shake. took it to dealer. They replaced Throttle body, (vsh? or vish? or some sensor + some other sensor i for got) however my best advice ..it should be clean time to time period. Just makesure do not over spray it off. Try to keep it dry and rub it off. You should be good to go.. always use "throttle Body cleaner" ..

Good Luck.

 

I might tell dealers to do it..its better to spend 200 of labor the 1200..

 

I understand what u saying ... if i didn't spent 1200 i would never know how to do it.. and at that time i had that kind of money to spend, to learn and become a geek of maxima,, from some angle
