how do you clean you mass air flow sensor,the code was 34 MAS i took it out didnt take it out of the plastic just sprayed both sides are you suppose to sprayup in the electric where you plug the wire.i took it to auto zone a couple of weeks ago and he said it was reading code 12.so and since I have had it its always sometimes didn't start like you would be driving and it would start all day then maybe one day you pull in and get gas and when you got back in it it wouldn't start then you would wait 15to20minutes later then it would start it just started acting up like this so I still think it could be a vacuum leak is there supposed to be a pvc valve on my gn 84 iv seen 4 different specs well I cant find on are you suppose to have the pvc valve on the vacuum hose
