1996 O2 sensor problems

so at least once a year my dads O2 sensors go bad. and we end up spending a ton of time trying to bend our arms around crap to get them in and replaced..
has anyone else had this problem?
if so how was it fixed?
thanks!

O2 problem

1. Does your Dad just putt putt around building up carbon?
2. Does he buy gas from the same place?
3. Does he put in gas additives?
You might change these things and see if it helps

well what do you mean by putt putt around building up carbon? lol
as to the next two questions he buys gas from where it is cheapest so yea changes in gas stations and no fuel additives or anything.. would you reccomend adding some? and how often?
thanks a bunch!

AS far as fuel additives go check the manufacture and read some reviews. Most fuel additives will say how often to use them (most are every 3,000 miles). Make shure you get the one to clean what you want to clean. There are ones that clean carbs, fuel injecters, or the whole fuel system. Also one bottle treats 21 gallons of gas on most additives. Only use when you have a full tank though! Hope that helps!:blink:
