Default How many O2 sensors
How many sensors are there on a 1991 Corvette L98?

I saw one while was under there (passenger side exhaust I think) which didn't look TOO bad to get to, didn't see any others...thanks!

On my 1989 there is one just after the header pipe flange on the drivers side. Easy to get to.

So what was it he saw on the passenger side? My 86's was on the driver's side also and had only ONE 02 sensor

It will probably be a pain to remove. I couldn't get mine to budge. I think when I have it at the shop next to get a new tire put on and oil change. I'll ask the shop guys if they could loosen then retighten the O2 sensor for me.

Sometimes it helps with rusted bolts to tighten them just a little and then loosen them up.

Never tried it with an oxygen sensor though.

There's a special tool for removing the 02; I know O'Reilly's loans it and maybe AutoZone too.

A few weeks ago I just used a box end wrench and hammer. The sudden shock of tapping on the wrench broke loose the sticking 02 easily.
