    yep. you need a special gauge set up. it places a T fitting on the fuel rail and your fuel line connects to it. the gauge connects to the T fiting to read the pressure. i'm suprised no one helped you sooner. i just got on here last night. hope this helps, but i'd guess youre having injector or ignition issues. the injectors start to act up in the maner you described when they are old and need replacing. i know theyre like 60 bucks each but its a good feeling knowing theyre good and you can hold your own against the new guy on the street when he pulls up next to you with his new intake
