Hey guys this is my first post on third gen .org! anyways I have a 89 camaro 2.8, the car bogs down/ misfires during acceleration, and when Im driving it will randomly cut off, and usually it will start right up, or sometimes I have to wait in the middle/side of the road for a a minute or two then it will start up. I have changed the plugs, they are black so I guess the car is running rich, I plan on changing the o2 sensor too, Do you guys know what this could be?
