I got home sunday afternoon and everything was fine. Monday morning we had a terrible rain storm. I start my car and it's misfiring like crazy and LOTS of white smoke soming out of the tailpipes. But damnit I had to get to work, and the military don't really care about car problems.

I checked the oil for coolant when I got off work and the oil level was really low, but no noticable film or milkiness. checked the coolant for oil and it was low, but not bad, and had a little brown in it, but it's been like that because I need a coolant flush really bad.

All my coilpacks look ok, checked all the wires, they look good. Could this be my fuel pump or oil pump? I really need to fix this so I can stop living at work on base, lol. Thanks in advance!

EDIT: The car is a 2001 Trans Am, headers, true duals, no CATS. I've had problems with the O2 sensors before, and nothing like this has happened.

I'd bet on one of the O2 sensors....any codes stored? Has it done it since or only when its wet outside?

I scanned the codes, and the only thing that came up was my AIR because it's disabled, and the mulitple misfires. The reason I don't think it's the O2 sensor's is because it starts misfiring immediately when I start it, not after the 2 minute warmup time. During that warm up time it ignores the O2 sensors, so I've pretty much ruled out the O2's, but I can check them anyway.

I don't know but what about taking a look at the plugs and plug wires, good luck.

I bet the plug wires are carbon tracking, old wires when they get wet they allow the spark to travel down the outside of the wire or the side of the plug. Once the water dries it has a carbon path it still follows, can't be seen by the naked eye in most cases. I would try plugs and wires.

Just noticed I have an oil leak from what looks like the back side of the block. So I'm assuming it's a head gasket...

The leak is more than likely you rear main seal

Go to auto zone or a mech shop get a comppression test done. BUT before you do that check and replace your sprk plugs. Your car can go from top performer to **** over night just bc of plugs.

If it is misfiring only when it rains, most likely the o2 sensors.

Did you extend the o2 sensor wires? I did that to mine, and water would get in there and make the car misfire like crazy.
