Car repairs

My car started to lose power with  the enging running rough and lousy gas mileage.   At first, I thought the problem was with the spark plugs, which I changed, but there was no net gain in power--and this past Friday, the car not only suffered loss of power and stalling, but also a sulfury, rotten egg smell came out of the exhaust. That's when I know the catalytic converter gave out.

I have to get around to volunteer, go to doctors' appointments, and simple shopping.  I will need the funds within a week so I can make my appointments.  This support will mean that I'll be able to do my civic duty to save the country from certain villains who shall go nameless and I'll be able to repay others at a later date when necessary.

It turned out that I screwed up royally.  The rotten egg smell came from the battery, not the exhaust, and the loss of power and poor gas mileage was caused by dirty fuel injectors and a clogged fuel system, not a clogged catalytic converter.

No, this is not a scam.
