Therfore there will be no pressure reading.



It's funny I get one too, but it's like -760hg, and goes toward the positive when I hit the gas. Not sure if it's reading something else, but it seems to work ok. When I accelerate, it will go towards the positive, but then go right back to -760hg when I'm done accelerating.
Oh yea make SURE that you have the Hot Wire selected to 01 in and 01 out, otherwise you will come up with some wierd problems! I know I had it selected on somthing different, and it screwed everything up! This might be the cause that my PATS light by the Contour badge in the middle of the dash stays ON!
One more thing the airflow should be at .5% or so on the idle, I've had mine down to .3% before after it warms up.
