You should be running premium regardless. Especially with the smaller pulley. 91 minimum to prevent KR, smaller pulley? 93 minimum.

If you think you're running rich, smell your exhaust. Smell rich? Now scan. Is the O2 sensor saying rich? If not, that may be your problem. After shutting down, wait 10 minutes or so, pull the vac line off the FPR, and check it for fuel in the vac line.

Edit:

I certainly wouldn't be putting a pulley on a car that isn't running right to begin with.

well i was offered to buy a puley for 50 bucks and have it installed and since i don;t have the tools or the know how to do it myself. Im gona take this offer up. Could low tires or low oil causes poor mileage because i haveto add oil every 2 weeks about and my back tires go to about 20 psi after about 2 weeks...slow leak

Lux..unless you diagnose it as bad, don't throw parts at it. When you get here..we'll take a look at the car. Because clearly I'd never slap a pulley on something that isn't running right to begin with. That would only make the problem worse.

I agree with

No buying parts at all. Not until firm diagnosis.

No pulley either. Put it on a shelf. With your oil consumption, that pulley is a bad idea. Not to mention the mileage problem.
