SES code - Is it the cats?
ok i will , im going to do it up this weekend........................so my cousin has a 99 z28 with hooker headers and borla exhoust with no o2's in the back . will this work for him to?????
it didint work ,unless i did somwthing wrong.....i put the foulers in with the o2 before the passenger side cat ..was i suppose to put it on the o2 right after the passenger cat???????????????????????????????
cool its been 2 days and staying off now . but sometimes when the car is off and i turn the key in the on position the light comes on and the code is that i have low circuit in the post cat o2 ... does that affect my chances????????
