recently it seems to want to loose power...as in i turn the key off momentarily. let off the gas and give it a little more gas, or just wait and it will seem to go away. seemed to be an electrical problem at first so i checked the battery and it is swolen, and corroded, so ill have to replace the terminals and battery, but also tried to hook up my obd1/2 reader because i am getting a check engine light. it will not connect. fuse maybe??? i know this sounds crazy but i put an aftermarket cd player in and i know how jeeps are have some power that has to run through the cd player... could this be a problem?
anyone know the blink codes in the jeeps?
thanks a lot guys/girls
