Came home from work yesterday and jumped in my Z for a quick run. First the check engine light came on so I pulled over, shut her down for a few minutes, and jumped back on the road. Then I noticed my boost gage was still at 0 and my blow off valve wasn't dumping, so I limped back home.

Was the check engine light on because she was running rich because of the pressure from the supercharger and why wasn't she dumping like normal????

I will in the morning.

She was running like the injectors were clogged (hesitation) but nothing drastic

Did you make a pass right before it happened?

Check codes first.

I wonder if a hose for the bypass valve came off? That'd cause a nice vacuum leak and leave the valve closed all the time.

Or the hose came loose from the boost guage. That would explain no boost on the guage and the blow off valve wouldn't work from the vacuum leak
