I wouldn't say it was lean rather fuel not combusting. Check plugs and wires. I had a friend this weekend with a 89 cavalier that was having the same issue. Pulled the plugs and the terminals were corroded and the plugs where horrible. Replace those and the plugs and no more problems. Check the current gap, over time it will get farther away and could cause the spark not to jump.
