MJRemi Posted December 8, 2010 Share Posted December 8, 2010 The 88 I just obtained failed the smog test last week. I replaced the MAP with a new one and started double checking all the air and vacuum hoses. The large diameter hose from the air filter box had a crinkle under the hose clamp so I dismantled the air box connections to see if I could straighten it out. Upon inspection, I saw a large amount of black gunk coating the entire end of the air box adjacent to the rear end hoses. It took 30 minutes to really clean all the crap out of the interior. It seemed like semi dry oil or grease. What would be the source of this greasy gunk and how do I prevent this in the future? Quote Link to comment Share on other sites More sharing options...
