Hey all

Because of my Pacesetter header, my front o2 sensor likes to get wacky every couple hundred miles. It just did it again this morning. The thing is, i have to drive 600 miles tomorrow, and i'm not going to get a chance to fix it before them.

Other than craptacular gas mileage, will this be a problem for the GA? Is there a chance it could cause component damage?

Well that sucks!!

Q. Why should I change a damaged Oxygen Sensor?

A. According to a study conducted by Sierra Research Inc. in 1996, worn-out oxygen sensors are the “single greatest source of excessive emissions for fuel-injected vehicles” and the second most significant cause of high emissions in carburetor engines. The U.S. Environmental Protection Agency (EPA) and the California Air Resources Board (CARB) have found that oxygen sensor replacement was required on 42%-58% of all vehicles that were subjected to an emissions check and found to be emitting high levels of hydrocarbons or carbon monoxide. Testing the oxygen sensors according to the vehicle manufacturer’s service procedures and replacing a sluggish or worn-out oxygen sensor can improve fuel economy from 10% to 15% (on pre-OBDII vehicles) and pay for itself in a year in fuel savings alone, while restoring your vehicle’s emissions to proper levels. And it can reduce the chance of an overly rich fuel mixture damaging the vehicle’s catalytic converter.

Thanks dude

Mother Earth can deal with me polluting my way along for a couple hundred miles. My cat's on the way out anyway. Just so long as it doesn't damage my engine. Anybody else have any extra info about this? I <3 my quad so much that i couldn't bear any harm coming to it.

At least i know it's not a LIM gasket leak. . .:heh:
