Codes P 0171, P 0174 - need help on fix '04 Deville
Hi all,
I've been hunting down the cause of these codes (171/174) and checked plenum coupling, MAF etc. Turns out it is an intake vac leak from the back bank breather/pcv hose that goes into the intake underside on the drivebelt side. the elbow rubber hose is bad. The Question is can that be Removed/ Replaced W/O taking the intake off? It is tight there!
Any help,tips or experiences with this will be much appreciated
thanks in advance,The wisdom here is great!
