My van starts up than It cuts off I have a p 1682.
 

I just got out of the big snow storm we had in the east and It's very bad because, I was stuck in the snow and I had to get pushed out off the snow to get to my house. I was in D and I just keep flooring it and I just whipping the car in the snow and got it to my house,but before that I had the engine light come on and then it turned off. I started the car and drove it up to my hill and turned it off. I think 4 to 6 hours later I tried to start it up again and then the car started up than It cutted off. I tried this tell I had the car running again. I had the car misfiring and I tried to give It a little gas and the Idle was jumping and hover with the car reving and stumbling. I pulled the codes and I got a p 0106 p 0107 p 01684 p 1682. I bought the new MAP sensor and then started the car again and it worked for a half of the day,but then again It was giving me a hard time starting up and staying steady and it cutted off again. I tested the battery and the alternator It was testing positive. I tested the battery from Advanced auto and the battery passed. I also just replaced the alternator with no luck. I am getting a p 1684 p 01682 code and I believe that's my PCM it's toasted and if that's the case how can I get this fixed. thanks.
