naw, dont bother cleaning it, you are just wasting your time, put you on a aonther sensor, just follow the vacuum line from the rear of the throttle body down, it is located just in front of your accumulator for the a/c. it uses a vacuum source and a voltage signal from the purge flow sensor, which is also in line, from the pcm, which commands the solenoid on and off. i see these all the time at the svt dealer where i work, i never paid for mine (hehe)
since i work at the dealer, but i also swapped the purge flow sensor too.. i just got my ira check, so now i am gonna get that kit from dta racing, plus add a few more goodies, i have the hook up at my dealership, and they are a motorsport supplier as well, woooooohooooooooo!!!
