I can't afford to fix FI

[SoapDuck@aol.com]

I really wish I could fix my FI but I do not have the money to fix it.  My
mechanic has tried to figure out the problem quite a few times.  Besides, all
of these sensors and regulators cost at least 100 bucks each.  There is no
way that I would be able to find the money to fix whichever one it is and
still be able to pay for other expenses that I have.  I am still trying to
pay for Homer in the first place.

Maybe, you all can help me.First of all,  The car is running rich. Also, I
took out the spark plugs and they were soaked in gas.  why is it doing this?
 Is there a way to narrow down what could be wrong with it?
