2G car does not move but starts HELP

[sillyme]

ok, i was driving around yesterday and when i hopped on the freeway, accelerated to 50 the car just stopped accelerating and started slowing down. the more gas i give it the worst it gets. pulled over to the side and let it cool off. starts right back up with a irratic idle. notice my boost gauge reads -12 instead of the normal -60 of vacuum. step on the gas and the car bogs and won't rev up. sometimes it even dies. so i towed my car back. any ideas? the day before i had a shop do a clutch and flywheel for me. but i highly doubt it's the clutch. maybe part of the install?

Probably just left a clamp or coupler loose. Do a boost leak test and see what shows up. That should be your first indication when you aren't reading proper vacuum.
