Im not 100% sure, but I am pretty sure the O2 sensors will make the car die, so my bet would be on the computer. Not sure of how much it will cost to replace the computer, but count on a pretty penny at a dealer.
The sensors are pretty easy to replace. No special tools needed; crescent wrench or specific size open end wrench. They will be located all along the exhaust system - only accessible from the bottom. You should be able to locate them from a mechanic's book if you have trouble. They look something like a spark plug with wires coming out of it. So, locate, unscrew and rewire. If you can do it yourself, you can save yourself about $250.
Further, I had to adjust the idle on our car because it would die when I tried to start it after it had sat for a while. So, try that; otherwise, take it to a trusted mechanic.
He is an example of car dealer rip off: I called a local Nissan dealer to replace a power steering pump on this same care. Quote? $717.50. Went to AutoZone and got the part for $170. Replaced it in 3 hours. And I am pretty sure no dealer will attempt to charge $180/hr. For labor. Think first before you take it to a dealer.
