My ka once had the same exact symptoms. It was the ECU, I knew this because I shorted it out, several times. It finally told me, "fuck you!" Once it wouldn't shut off when I turned it off by the key, I replaced the ECU.

Problem was then solved, along w/ several other problems.

Im back, so i found an ecu on craiglist, the front sticker that says whether it is an e5, 62, or 63 on it got ripped off, the guy knew it came out of his s13 sr20 so i figured as long as its not a notchtop it should be interchangable besides o2 sensors. so i got it and plugged it in and yes! she started up, but only for a moment until it sputtered to a stall after 2-3 seconds. so i started it again but this time gave it gas and it wasnt a clean rev, it was full of break ups and wouldnt rev high, just sputter and i let off at all it would die. So i slept on it and came back today and started it up with the maf unplugged. This time it ran a little smoother, idled smooth but would still sputter under any type of throttle(all of this is at neutral under no load) so i plugged the maf back in and started it and it ran worse like the day before. So i unplugged it, started it, let it idle then i went into the engine bay and plugged in the maf with the car running and it immediately died. what does this mean? is this ecu not compatible? is the maf broken? it never had this problem before, and my previous ecu was e5 and this one has an led in it so i know its not an e5. HELP!!
