Passenger side. Sensor closest to the engine, I believe.

Dang it Mark...You always know this stuff. I almost PM you on this before I even started this thread!!!!

Well I don't know. I replaced bank 1 sensor 1 according to this diagram the passenger side. I let a mechanic pull codes the codes again cause it didn't fix it. He said it is throwing the bank 1 sensor 1 code still and that I replaced the wrong one. He says bank1 sensor 1 is always the drivers side.....So were did you get this diagram?????

That's from the '99 VX repair manual. The sensor is not always the problem. The sensor is sensing a problem somewhere else. I'm on all my original O2 sensors after 252,000 miles, so they are not prone to failure.

I'll look up info on that code later tonight or maybe someone else can post it sooner.

A mechanic friend of mine just replaced the o2 sensor on the driver side. I haven't been able to drive it yet but he said the misfire is gone. (and he replaced the plugs too but said they were not fouled).

I'm on my way out the door to go flyfishing for the evening, but I got the info in just a few minutes. I'm positive Bank 1 is the pass side. If that code comes back, here's the info-
