yes i have the 98 pcm...the 03 was different and didnt feel like rewiring it when its not needed to do so.... the only thing i swap out was the blower to my 98 blower.. the new one had a drive by wire throttle bodie and i cant use that... other then that all i did was hook up all the sensors and mount the blower and i was done. and yes i put a new gasket on. didnt have to take the throttle body off to take the blower off, you dont have to. and i know the throttle gasket is fine. it worked fine before it blew.
and how do you get a leak with a new blower gasket, and im sure you cant mount it wrong, unless your just plain stupid! so lets hear some more thoughts!
