I have a V-6 2.5. I recently discovered that i had a vacuum leak after trying to discover why my engine was loping at idle. I discovered that the check valve and one of the vacuum chambers underneath the intake manifold had both had a nipple busted off them. i ran a new vacuum line bypassing the vacuum chambers and it is still loping at idle. is this because i'm bypassing the chambers? How important are these chambers?
