Pinguiclia

Recently I replaced the motor mounts and transmission mount on my '92 Camaro (V8 305 TBI) and now I am experiencing intense vibrations throughout the whole car. When you start the car cold the RPMs jump to 2,000 and in a few minutes it settles down to around 1,000 in park or neutral, right around this time is where the car will start shaking violently like bad enough that everyone in the car shakes. Drop it into drive and the RPMs drop to ~800 and the shaking will slightly decrease, but if you're at a dead stop and slowly release the brake the car will move but it shakes you back and forth until you're completely off the brake. It feels like a misfire but it's not I've replaced the plugs (0.35 gap), replaced the wires, checked compression in all the cylinders and made sure I'm on TDC. And to top it all off the car is running rich... I'm at a loss at this point and would appreciate any help.

Idle flash sounds like a vacuum leak

I got the vacuum diagrams from Chevy86 and I'll check all my lines when I get home.

Nothing is sluggish and it seems to have every ounce of power it offers. Dead stops or from rolling it'll accelerate fine and runs smoothly once you're past about 25MPH. If you get below 25 you start to feel the shaking and vibrations, today when I started my car I noticed when it was in the 2,000s from the cold start it was completely smooth not one shake but as soon as it started to drop the vibrations started and once it settled it started to shake..
