that is also the same code that is haunting me. P1491 is the EGR valve lift, at the dealer it's $300 bucks to replace. I dont know if it's ok to just clean it, but mines on order.

you can easily clean the egr without even taking it off.....but your boost is probably forcing it somewhere it doesnt want to go....

again, go to the forced induction forum....a little farther down the main page.....

He's getting an EGR code, not a MAP code.
