Question 1

Who is spectra premium?

Accepted Answer

Spectra Premium is a North American manufacturer and provider of automotive aftermarket parts for passenger, classic and heavy-duty vehicles.

Question 2

Can I drive with a faulty oxygen sensor?

Accepted Answer

We recommend against driving with a bad O2 sensor as the powertrain is not running on the correct fuel mixture.

Question 3

What happens when oxygen sensor goes out?

Accepted Answer

Will a bad O2 sensor cause rough idle and loss of engine power? You bet. Moreover, you may also notice poor acceleration, engine misfires, and even stalling. Bad oxygen sensors disrupt all kinds of essential engine functions, including engine timing, combustion intervals, and air-fuel ratio.

Question 4

Should I replace all O2 sensors at once?

Accepted Answer

It is best to replace both corresponding sensors on each bank if you have a V6 or V8. For instance, if your bank 1 upstream sensor has gone bad, you should probably also replace your bank 2 upstream sensor. If you don't, then it is likely that the bank 2 upstream sensor is going to go bad soon.

Question 5

How long can I drive with a faulty oxygen sensor?

Accepted Answer

Yes, you can drive with a bad oxygen sensor if you can still start your engine and feel little difficulty driving. But don't leave it alone for over a couple of days, as it might cause safety problems and lead to the malfunction of other parts of your vehicle.

Question 6

Will a new O2 sensor improve performance?

Accepted Answer

The EPA says that replacing a bad oxygen sensor can improve fuel economy by as much as 40 percent, so clearly that is one place to look if your vehicle develops a greater thirst for gas.

Question 7

Could the oxygen sensor mess up any shifts with the transmission?

Accepted Answer

When the O2 sensor is not working properly, this will cause false readings to be relayed to the computer causing inaccurate adjustments to be made to the intake and fuel system in your engine. Any of the above conditions may cause inaccurate shifting points to be made by your car's transmission control module.
