Contour Enthusiasts Group Archives Forums General Troubleshooting CEL w/ P0171 code, Stalling.

So you are saying the intake manifold gaskets caused a vacum leak? yes, that can cause a stall. Can you better explain how the gaskets work (or don't work) and what the problem is?

Where do they leak? I should be able to find it if I have an idea where to look.

Thanks.
