Well, crap!! I got in the car to drive it into work today, and the check engine light was on. It wasn't on when I parked it Wed. night. It is running fine, just that blasted light. Doesn't make sense that something would go wrong just sitting in the shop. I guess I'll have to bite the bullet and buy a scanner after work and see what went south. So much for going for a cruise after work.

Unusual for a Gen 2. Gen 4 seems on an almost daily basis.

I'll take a guess...o2 sensor.
Are we to assume that it is a 2002 Viper?
My wild guess-of-the-day-is: cam sensor.
Grab a code reader and let us know!!

You win the prize!!!! Bank 2 sensor 1. Cleared the code and went for a 60 mile drive for a couple beers, and no light. It was doing this when I first got it.? All sensors tested OK, so I guess it's just a glitch??

I'll also guess it's no glitch. They seem to die slowly so be prepared to replace it. It's not a big deal.

So your code was a P0155 (passenger side upstream, before the cat), mine was a P0135 (driver side upstream, before the cat). Mine came and went for a couple of weeks and then just came. I was skeptical at first also so I switched both upstream sensors and I got the P0155, so I was convinced my O2 sensor was bad.
