i just bought a 1998 sahara with 113,000 mi. the gas ran to empty on the way home from buying it. now it idles high and bogs out if i dont let it warm up for about 10 mins. does anyone think i may of sucked up the shit at the bottom of the tank and i need to change the fuel filter??or do u think if i drive it that it will flush all the shit out and stop bogging and idling high and low???also the air filter is starting to scream when i start it?? i havent got a chance to drive the jeep since ive had it, do to not having a license, but rest assure ill be getting my license back in a month and have it back on the road..also the brakes seem seem spongy and when on a incline my front brakes lock up but my back brakes still roll alittle and wont grab completely? i also have a after market top, not sure what kind but my back windsheild wipers and defroster doesnt work. could i rewire it to make them work?? any advice i would really appreciate it..
