just realized that the vacuum line to the MAP sensor is sucking flat. anybody got an idea of what this will cause. im sure its why it is running rich at idle, but just wanted to know some other opinions of what it might be doing??

 

I would replace the hose with a new one and see if that helps. Probly just a week piece of hose.

 

yeah, i know how to fix it, i was wondering what it will cause as far as problems.
