Hi FixKick:
In continuation of trying to see why the engine is running weak and misfiring, as suggested, I did vacuum test today. First, the line that goes to the orange color fast idle VSV got tested, and showed 17 inch vacuum.
However, there is no vacuum on the line that comes to and goes from the EGR VSV. Is this normal? I tried the bottom vacuum hose that goes to the throttle body; no vacuum! Then tried the top line that goes from the VSV to the P side of the EGR modulator; no vacuum either.
Is there supposed to be vacuum on those lines? If so, where should the vacuum be initiating from?
Thanks for your time in advance.
