This is an 89 v6 2.8L Camaro...

When I'm at a light or just idling, I sometimes have this issue where the car will lightly accelerate from about 500-1000 rpm. Obviously, I just keep the brake depressed, but the issue is pretty intermittent. What could be causing this? I realize that there may not be a simple answer, so I'm just looking to be pointed in the right direction of what to look for.

On a possibly related note, there seems to be very little power in the first two gears. The acceleration is terrible, and I have no idea where to start. What could be causing this, and are the issues related?

Thanks!

 

During acceleration does the engine seem like its skipping or really sluggish in the first two gears? could be a vaccum leak until the engine is running in a higher rpm pulling less vaccum sucking less air. Would start there
