Misfiring and Shaking I was driving my 2000 SS today in the downpouring rain, and all of a sudden, the car started misfiring and felt like it was running on 4 cyls, and it was shaken quite a bit, and then i noticed the SES light came on, i noticed once it stoped raining the car ran alittle better, checked the air lid and only a little bit of water made it in, got it home and plugged in my scanner and got two trouble codes, one said Misfire detected on mutiple cylinders and other one said 02 sensor high voltage deteteced bank 1, i cleared the codes and it ran fine for 30 mins and then, it acted up again and ran like crap and the SES light is on again, what the heck did i do to this thing? i only hit a few puddles, nothing bad, but it was really bad out.

if it was raining hard you may want to check the connections on the extensions. it is well known that they sometimes get wet during a heavy rain or when there is a lot of water on the road. just pull the connector apart and use some air to dry them out. But it sounds like you got her running right.

My car also hates the rain..... ive had it fall on its face before during heavy rain and then it would not start. it was doing it damn near every time it would rain for a couple hours.... i could not figure out for the life of me what the hell was getting wet so one day i got out the hose and soaked my car and popped the hood. the only thing i could see getting water to it was my computer so i put a zip lock freezer baggy over that bastard and have not had a problem since...coincidence? maybe, although it looks retarded it looks less retarded than falling on my face at 2000 rpms...lol

I had the same problem with the rain. Pulled the 02 sensors out and water came out. Now a couple days after with no rain my car has been doing the same thing its almost like clock work now I start the car runs for about a minute then starts bucking and misfiring and then it stops and runs normal. what could cause this?

try the spark plug wires, i had the same issue, my spark pluge wires were rusted on connections to the coils and to the spark plugs, i changed them and ive never had the prob ever since

Where can I go to get a PCM reflash? Is it expensive to do? I checked all the spark plugs and wires and they are good and the o2 sensor connections had no water in them. This problem is driving me crazy.
