Hi Guys I have a 1997 jeep Cherokee 4.0 l aw4 tranny 4wd and the check engine light is on and I have a code 45 and can't find anything that tells me what a code 45 is does anyone know what this code indicates. thanks
 
How old is the battery, does it happen to be the original :D If so replace it. I did all three of ours in march or so, three new red tops, 98XJ and Two 97TJ's... advance auto has them on sale from time to time for like $100 or so... My 98's battery was OK but when the redtop went in the engine sure spun over alot faster...
