Help fast!!! Car missing In rain!! Ok drove my car in the rain today and now I'm on the side of the road with my ls1 missing. I forgot to tape upy rear o2 sensors when I put my headers in and they are dangling down and soaked. Is that my problem for the missing?
When I had my ws6 I ran o2 extensions and everytime they got wet the car missed real bad. I got tired of messing with them and just re-pinned the PCM to where the rear o2 sockets red the front and I could use the nice, factory length o2's and I would never have to deal with missing again.

Check for any exposed wires getting wet for your Front O2s.
When I did my O2 extensions after headers, I zip tied them so they wouldn't dangle, but I was either too dumb or too anxious to start driving that I didn't realize a part of the extension was touching some part of the exhaust pipe. Over time, it burned through the heat shielding and burned right through the wire insulation so bare wire was exposed. Everytime I washed the car or it rained, I'd get misfires. When I discovered it, I tested it by keeping the car on, taking a spray bottle, and just spraying a little bit at that exposed wire, and I could immediately hear the engine misfiring.
I just bought the Bosch Corvette Rear O2 sensors to replace the front O2 sensor + extension, and this time ziptied the excess wire more carefully and problem solved.
