    Well it is definatly running way to rich and considering that the vehicle is a 2002 I assume you have a check engine light on

There are many things that can cause this problem and it would take too long to try to diagnose without the proper equipment, I.E. OBD2 Scanner. There are just too many engine controls that could cause a misfire. You will have to take it into a shop for an engine diag. This will probably cost you in the range of 150-200, this price does not include the solution, that is entirely seperate. A scanner needs to be hook up to zero in on the problem area, and from there the problem can be tested appropriately.

replace ignition system, start with coils, and coil pack housing under engine top cover. The plastic coil cover may be arking out. some people will tell you to look for "spider webs" on the plastic cover, don't you believe it!!! They go bad quite ofter and cost $50 a shot. also check your plugs, ONLY use autolite or ac delco REGULAR plugs, avoid bosch AT ALL COSTS.

I happen to own a 2002 alero, and alot of people says the same thing about theirs. You may need to replace you head gasket and run more antifreeze than water.
