We have a 96 Neon with two oxygen sensors. According to one mechanic, the one by the exhaust pipe was not working properly and should be replaced. Another mechanic said it wasn't necessary because it would only affect emission. The computer would automatically follow the preset air/fuel ratio. What is the long-term effect of not replacing the oxygen sensor? Which mechanic is correct? Thanks > We have a 96 Neon with two oxygen sensors.

The air/fuel mixture in the cylinders is adjusted by the computer depending on how much oxygen there is in the exhaust. The car will run if the oxygen sensor is not working but fuel efficency and emissions will suffer. I think it could also lead to carbon buildup in the engine if there is too little air in the mix. The preset fuel mix was used before cars had oxygen sensors and computers but it was adjusted to some extent by valves and things inside a carburettor. -- ------------------------------------------------------------------------------ William R Watt National Capital FreeNet Ottawa's free community network homepage: www.ncf.ca/~ag384/top.htm warning: non-FreeNet email must have "notspam" in subject or it's returned Mechanic #1 is speaking in your interest. Mechanic #2 may think he's helping you, but he is not. You might end up saving more in fuel and repairs by changing it. It's not hard to change either. Perhaps you could do it yourself. Be prepared to change the other one before too long as well. >Mechanic #1 is speaking in your interest. Mechanic #2 may think he's >helping you, but he is not.

Absolutely correct. Thank you both for your input. This helps! > We have a 96 Neon with two oxygen sensors.

With reference to a previous posts about a tuneup on another vehicle. if you are going to have the mechanic replace the OS, get a cost estimate first. If you are going to replace it yourself (and you can if you are the least bit clever with tools), it will probably be your cheapest way out. what was the original complaint? what did the first mechanic say was wrong with the oxygen sensor? Kinda' looks like an ASE test question..... Who's right? A.) Mechanic "A" B.) Mechanic "B" C.) Both Mechanic "A" and "B" D.) Neither Mechanic "A" OR "B" wipeout64@hotmail.com wrote in article <1131370679.159078.225350@g49g2000cwa.googlegroups.com>... > We have a 96 Neon with two oxygen sensors.
