Hi all,
(backstory)
Car wouldn't start, got NRMA out to jump start, and he tested the battery while car was running, to check alternator (14.## volts), he said alternator was OK, so we drove it home. Next morning, went to supercheap to get a new battery, car started OK, but at supercheap they tested battery and came back 'bad'. Bought a new Century battery, installed it....
Basically car is idling/stalling, which I 'think' might have to do with replacing the battery. Starting the car, it would start, then die. Only way to get it to start is to apply a little accelerator. After a few seconds, remove acceleration and car would idle, poorly (probably around 500rpm +/-). If I accelerate (1-2k rpm), and release foot, rpm would drop right down <500rpm, almost stalling, then it would pop back up again.
I have heard that replacing a battery can turn the ECU dumb, causing it to have to relearn, but was wondering if there's a chance there might be something else wrong with it?
I thought maybe fuel was dirty, but Mum said she fueled up a few days ago, but didn't notice any issues.
I checked air filter in case blocked, didn't seem to bad, a little dirty, but nothing suss.
Checked oil in case was low, and maybe causing friction in cylinder.. probably very unlikely, or pointless, but figured why not, while I had the hood up. (oil was 50% full, but needs changing)
Could be dirty sensor, haven't checked.
Anything else, or very likely that it just needs to relearn? If so, what's the best way to go about it? just start car and leave it idling in the drive way? Mum needs it for work, is that going to be an issue driving it ?
I tried an OBDII reader too, jut one of those ebay jobs, with the Torque (lite) Android app, but I got an error in Torque,

still loaded into Torque, but pretty much nothing would connect (except acceleration, which maybe ran off protocol 3, which I think Torque said was OK). I tried OBDLink, but wouldn't work unless I had one of their readers. Also tried BlueDriver, but wouldn't detect my reader :/.
Note: i just found this entry on wikipedia regarding the QG18DE engine;
OBDII – On-board Diagnostic System (codes can be read/erased by a variety of readers, e.g. Actron blaZt). Nissan Pulsar N16 Models without EuroOBD in Australia do not have OBDII.
If the car doesn't have OBDii reader.. what does it have? It has the port under the dash that connects a reader, so it must take something ?
Vehicle is a 2003 Nissan Pulsar N16 Auto 1.8L QG18DE engine.
Thoughts ?
Thanks in advance.
