How can I fix a P1320 on a 2008 Mitsubishi Outlander XLS V6? ?

How can I fix a P1320 on a 2008 Mitsubishi Outlander XLS V6? It has 128,000 miles, I went to turn on my car this morning and it displayed a Service Engine Soon Light. Went to Autozone they pulled a P1320 Code "ASE certified master technicians have seen this issue on your type of vehicle and the most likely solution is: Replace Engine Control Module (ECM)" How much should a mechanic charge to fix this? Do any ECMs come with a lifetime warranty? I had a Mitsubishi Dealer Replace the ECM two years ago. 

Update:

After two days the Service Engine Soon Light has gone away. Should I not worry anymore? The light has gone off so does that mean it is not a serious problem? Could it have been a fluke glitch and now it has fixed itself therefore the light turned off? What would you do in my situation?

    It's not the ECU. It's likely a bad coil on #5 cylinder.

    I'd take it to the dealer.

    Autozone is in business to sell parts whether you actually need them or not. Take your car to a REAL mechanic and have it serviced properly.

    Error code P1320 means there is a problem with the ignition coil or the wire to the ignition coil.

    If you want to spend money on a new ecm then go for it. I'd be troubleshooting the ignition coil

    A trouble code does not tell you exactly what is wrong and what needs to be repaired or replaced. It just indicates what systems are effected and more trouble-shooting should be done to identify the precise trouble. The suggested repair given by Autozone may or may not fix it. What's more, most electrical parts cannot be returned once they have been installed and no ECM's that I'm aware of come with lifetime warranties.  Therefore replacing the ECM without properly diagnosing the problem is risky and definitely costly if it doesn't fix the trouble. If you can't afford to have a shop perform a thorough diagnosis and you lack the required tools, skills and knowledge yourself, then you're playing a guessing game.
