Trooper throwing codes
 

Hello. New here from South Dakota. I'm looking into a 1998 Trooper at dealership. The salesman is honest enough to tell me right off the bat that its does have some codes its sending. I think most are o2 senors or related. Should any of theses make me run away from this buy? I am somewhat capable of fixing problems. Thanks..

hey bro, how much? and ill see if i can get with my dad and see if he can remember the codes from my moms. she has a 1998 as well and so far we have done ERG and both O2 sensors.

Its a 1998 with 141000 miles. They want 3900. Is this going to be a bad buy? Not sure what to expect out these motors. Have read some really good reviews about these vehicles.
