Hello, try replacing the oxygen sensor, if you have over 100,000 miles. It starts wearing out about then, and can make the on board computer think the engine is running lean and compensates by making it run rich. Part cost about $40-$55. Hope this helps you.

An oxygen sensor is part of the emissions control system and sends data to the engine to help the engine operate smoothly. When defective, an oxygen sensor can impact your fuel economy, dropping by as much as 40 percent.

Oxygen sensors are important to have in a car. The price of one can run from $40-$200+, depending on where, what model, and any other specifics, when bought.

On July 3, 2008 I was quoted $120 to change one oxygen sensor on a 98 Silhouette. Since the part is probably around $80, I would guess $40 is for labor. This is in Texas. Gary

Disconnect the wires, and unscrew the O2 sensor. You might want some wd-40 to soak up the sensor's threads before you try to remove it.

Between $40 - $60 seems typical. The actual cost will depend on specifics of your vehicle, such as which engine it has.

Halbert's company saw business triple each year from 1989 to 1991. In 1991 the brothers were named to Dallas's "40 under 40" list, featuring the city's top 40 executives under the age of 40.

40 Percent. molecular mass of MgO = 24 + 16 = 40 percentage of oxygen = 100 x 16/40 = 40 .

The sensor itself is going to range from $90-110 bucks at a part store (more at a shop of course), and then it is a pretty quick dig, I hear ... my shop was going to add $40 bucks to do that.

You might have to take the heatshield off of it first, but I'm not 100% sure. You should definitely use some WD-40 and let it soak around the sensor for a day or so.

I was told it varies with the vehicle's Make i have Ford i was told to drive 40 miles we drove 55 so we were told to drive 40 more miles haven't done that yet. i think the o2 sensor has to accumulate enough carbon before it's considered "Ready".

The amount of oxygen supplied by rainforests is about 40% of the earths oxygen.

Your most likely cause is a throttle position sensor, or a fuel problem, or restricted air flow.... that is a tough one.

Its my understanding that the 92 and 93 Tranny is the same for the two years. It might make a difference if one is a electronic 4-wheel drive and the other is not.

I'm not sure about 40% but it WILL reduce gas mileage I'm not sure about 40% but it will for sure reduce your gas mileage. 40% does extremely high for just one O2 sensor

The cam sensor on a 1996 Mercury Villager cost about $35 to $40. The sensor is actually manufactured by a Nissan subsidiary.
