95 geo prizm CEL on who can scan this?

well the free scan at advanced doesnt have the obd1 adapter for a 95 geo prizm, so now who can scan this for cheap/free. i dont mind having to work it off, i just dont have both the cash to find out what it is AND fix it.

my few guesses are the 2nd O2 sensor i unplugged for the flexpipe repairs i did some 3k miles ago. the rattling noise sounds like lifters, maybe timming chain on the 180k motor. its the beater/wifes car. until my jetta is someday finished i have to drive this. i also smell some gas and see that teh evap tube rusted and fell off near the tank. so there are possibilitys.

anyone that can be of help would be great.

i know theres things i could fix on it but i need to make sure the CEL is not serious damaging.

bump for help?

if its that many things that you know about, why not trace some of the obvious stuff down and see if it goes out. you dont want gas leaks anyway and you could just get a bung welded back in for the 2nd o2.

id scan it but i dont have the import cartridge or cable.
