Just got a 1999 with a KB 2.1 on it. Was driving and ran it through 3rd gear. When I stopped again the vac boost gauge was not showing any vacuum. And the fuel pressure was registering higher than normal at idle. Looked under the hood and the supercharger bypass is staying open so I know the car is pulling no vacuum. Runs perfectly fine. Where should I start looking for what is wrong? Sprayed some brake clean in a few areas to see if it idled up and nothing.
