Ya only if your 02 light shows up..if it doesn't, then it's cool!! How many miles since you changed the plugs??Originally posted by 633csi@Jul 30 2003, 09:00 PM
I read in another forum that a faulty 02 sensor can contribute to low gas milage, My car isn't doing to well in that department so i was thinking of checking the sensor.
Have the dealer hook a dynostic check on the OBC..hmm 83?? Not sure on your ride's OBC but you could have a dealer look at it..Originally posted by 633csi@Jul 31 2003, 04:46 PM
it has been a while since the plugs have been changed, i just checked them yesterday and they were pretty bad. I am going to replace them, but im sitll just wondering how or if there is away to check the o2 sensor to see if it is comtributing to the problem. No the light isn't on, but in the link you sent me it said they get worse with age and i own an 83.
