Default Rough start and idle

This started last week. I started my car to let it warn up while I got ready for work. When I came out the car wasn't running. I tried to start it. It would turn over but not start. I did the basic checks. Main relay good, fuel pump good, battery good, but the spark wasn't there. I check the spark plugs. They looked good so I check spark at the end of one plug wire. I got nothing so I started checking where I lost it. No spark at the coil. I decided to replace the coil. The car still wouldn't start so I removed the Icm and took it to o'reilly's to get it tested. It failed so I ordered a new one. I installed the new Icm and the car started right up. I let it run a while. When I came back to the car it was surging during idle. I went to take it for a drive. When I pushed on the accelerator the engine shut off. I got it started again after a few tries. I noticed that when it was turning over to start I would loose power for about a half a second and then continue trying to start. I can't get out of the drive because everytime I push the pedal the engine shuts off. Right now it's hard to start, rough idle, shuts off and no CEL. I am going to remove the cap and rotor to make sure I didn't forget anything. Any help would be great.

Have you checked your MAF sensor?

surging idle usually means a dirty or clogged IACV or throttle body. check this video. http://www.google.com/url?q=https://...vpz2vf473q0t7Q
