    Got the car running - but it doesn't want to stay running

    Can you run an S50 O2 sensor in the S50 manifold just to get it running until the mid pipe is on it?

      Checked the fuel pressure within spec. 50psi with no motor, 40 with the car barely running.

      It starts and won't hold idle but with rev. I am going to towards vaccum leak. All the sensors are hooked up. I really don't feel like pulling the valve cover to re-time the vanos.

              The MAF is brand new, less than 10k miles. Im going with vacuum leak. I shall continue my search.

                      It acts goofy even reving it.

                      ICV vacuum leak maybe.
