hey everyone- i searched but could not find anything about this noise that i hear most of the time after i shutoff the max, after its been driven for a while. its a higher pitched whirr that seems to come from the exhaust. it starts as soon as i shut off the engine, and ends usually within 8 min. ,
anyone heard of this?
btw 96 auto 84k
help is much appreciated
-D
