Unhappy P0103 w/ P0302 and P0304 - HELP!

It has been raining and flooding streets in the Chicagoland area, and I would normally expect a P0103 in this weather, but this time, the car can barely stay running. The major problem happened after hard accelleration last night while it was wet out of course, the car actually shut off, and luckily I was about a half a mile from home, so I got it to stumble the rest of the way home.

Today, it is still raining, but I let the car sit over night and went to start it... same problem: barely stays on. I have 5 total codes P0103, P0302, and P0304 with two pending codes: P0302 and P0304

Any ideas? I really dont want to take off work tomorrow to mess around with this.

Maybe clean the MAF and check your air filter. Good luck

Already cleaned the MAF and took a look at the air filter... no dice. I am getting it towed today.

Got it in the shop - something happened inside and we arent sure what yet. They managed to get it running ok bu tremoving the plugs and regapping them. Somehow, they were bent down (the idea is that maybe water loosened up some carbon and landed on a plug). Anyway, I am NOW getting even compression across all cylinders and it is still ticking. They are goign to tear it apart after getting authorization from the insurance company.
