PLEASE help!! why would water cause this?? I know... long write but I NEED some help please!
One day it had been raining out and I took my car to go to the bank which is only about a mile from where I live. As soon as I pulled into the parking lot and got into line at the drive through i noticed the car was idling rough, and at about 100 rpm's lower at 500 instead of 600 rpm's. My service engine light was on but always is cause of headers and no rear o2 sensors and I removed me EGR pump. when I took off the car had NO power! after a while the problem just went away and nothing happened for about another month when I took it to an automatic car wash. It was the kind that sprayed up from underneath when you drove in. As soon as that happened my car started idling rough again, and shaking the whole car. so I shut it off. when it was time to leave the car wash the problem was still there. when I took off the car had NO power again. I seen the tac say it was at around 25 to 3k rpm's but i didn't sound like it when taking off. soon after the service engine lights started flashing! I knew that meant something serious was wrong so i pulled over and shut it off. after a while i started it back up and the SES light wasn't flashing anymore but was still running funny. I drove over to AutoZone that was close by and got the codes read. there were 10 codes! 8 or 9 were for the o2 sensors and EGR and one was pending and said "Random Multiple Cylinder Misfire". after a while i started it back up and it drove fine, the power was back and it was idling good. I thought it may be something with the transmission trying to take off in second or something so I tried manually shifting it but it didn't seem to help. anyone know what could be wrong?? please help if you can!

sounds like your plug wires are jumping fire. Wire are more prone to jump fire when wet. You can start the car and spay water on them with a squirt bottle and see if it starts it again. I am an auto tech. and i see it all the time at our shop. Hope this helps. Penning
