02CamaroinCali

I have a 02 1LE Camaro SS, mac mid-length headers, and a cutout. Every time it rains I get misfires down the entire left side. After a good rain it continues for about a week then goes away. I have taken it to the dealer a couple of times only to be told I needed a fuel additive, which i tried to no avail. I have changed the plugs, wires, Idle Air Controller, fuel filter, checked for vacuum leaks, and tapped on the computer with the back of a screwdriver to check for loose wires. Does anyone have any other suggestions? This is driving me nuts, any help would be appreciated.

Thanks

Brandon

sounds like maybe your 02 sensors are getting wet

When it is running good try unplugging one sensor at a time or one coil at a time and see if you can recreate the problem. If that doesn't work then try getting the car wet and see if you can spot what is getting wet.
