Is this normal also i think i have a vacuum leak somewhere and i hear something hissing on the turbo side of the engine. When my dad and i replaced my fan clutch this morning i drove it around to see if my milage improved. It did it went up to 15.2mpg but when everytime i came to a stop light the mpg would start dropping down to to close to 13mpg. Also when its idling its rought (my guess is vacuum leak)

Car is Automatic

Thanks

idling doesnt help MPG. your using fuel and going no where... so its essiantly 0 MPG.

and if you "think" you have a vaccum leak, then start zip tieing all of your lines.
