Misfire and CEl after plug change.

Ok so here is the story. I have a 04 Legacy with the EJ251 SOHC. It has around 104,000 miles. I decided to do some tune up work to it to try and make it last longer.

So, last night I changed the plugs out with NGK plugs that are listed in the Chiltons manual as being compatible. I also was trying to get the timing belt changed too. But we didn't have the right tool to hold the crankshaft pulley, and it accidently got turned counter clockwise a little bit.

I gave up after that and I finished putting the plugs in. And once that was done I fired the car up. And now it spits and sputters like crazy. I did the plugs one at a time so as not to mess up plugs wires. So i know the firing order is fine.

Now, I did suspect that Cylinder #2 was not firing. I pulled the plug on it and it was gas soaked. I swapped the plug with an old one and the same affect. I than swapped plugs wires from 2 to 4 and than it seemed like it was doing the gas soaked plug on cylinder #4. So than I swapped wires again back to #2 and put an old plug in the wire aand attempted to start it to see if I had spark. And it did. I tried both the new plug and the old one. Both had the same results.

Now I am lost. The car was running fine before this, I just wanted to do a tune up. My questions are:
1. Could the timing had possibly jumped when the crank pulley accidently got turned counter clockwise,
2. Is there anything else that I could check before jumping in and pulling everything apart to check the timing.

Any help would be great. My family and I are supposed to go back home tomorrow, so I am trying to get this fixed asap.

Thanks.
