Just wonderin.. Ive got a friend who says that their car is runnin rich.. aparently it has problems starting cuz the plugs get flooded and when your drivin it if you go to stop you have to give it gas otherwise it will stall out. Its got a new head gasket, timing belt, valve cover gasket, and 02 sensor. What would be causing this to happen? Any help will get rep'd. Thank in advance

** Edit **
Thought it would help if I gave you this info.. the car is a 95 teg with a B18B1 in it. lol
