Bosch o2 sensor
I had a miss for sometime in my 94 coupe, I replaced knock sensors because of getting code 43. Timing would retard and it would spit and sputter. Replaced plug wires and plug. I noticed a rich condition on the left bank when replacing spark plugs. I replaced left o2 sensor with a Bosch o2 sensor and still had a miss> I chased this miss for 2 months. I unplugged the knock sensors and it ran great. I eventually found the miss was from the Bosch O2 sensor. After 2 Bosch O2 sensors were replaced I warn anyone that tries to use a Bosch O2 sensor in a Corvette not to. Please spread with others

I just read that within the last week. Somebody had a problem with weird readings from a Bosch and replaced it with an AC Delco and all was well.
Come to think of it, I put a new Bosch in mine a couple of weeks ago because it was easy to get at the local AutoZone. It has run a little funny lately. Hmmm....
