That's the problem. In most cases, the pressure sensor is not the problem, 
and "adjusting" it just means that you've now lost the factory calibration. Yes, 
you can mess with it, and a lot of people do. SOME of those people really 
know what they're doing and do it with real understanding, but just adjusting 
one part, to make up for a problem you don't understand, is the gateway to 

Most people who do this end up either junking the car, installing carbs, or 
just running extremely rich and fouling the air.  

It's not an approach I would ever recommend.
