Hi all, Really hoping someone might have an idea on this issue. I've tried Pulsar specific forums but no luck. (backstory) Car wouldn't start, got NRMA (roadside assistance) 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 get a new battery, car started OK, but at autoparts store, they tested battery and came back 'bad'. Bought a new 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 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) I have heard that replacing a battery can turn the ECU dumb, causing it to have to relearn. I've come across a few procedures, but none seem to work; http://afiaustralia.com.au/images/stories/N16_pulsar_idle_fault.pdf https://ricksfreeautorepairadvice.com/nissan-idle-relearn-procedure/ https://www.youtube.com/watch?v=CR-AjHCslhs https://forums.nicoclub.com/how-to-ecu-relearning-procedures-t445702.html Following the steps in the 1st link, step #6 says to "disconnect Throttle position sensor (brown in colour) connector", but there is no brown connector, just a single green one. A service manual I found shows a diagram with a brown (throttle position sensor), and a Grey (closed throttle position switch), but our Pulsar just has a single green connector. When I disconnected / reconnnected that one, the accelerator went limp, couldn't rev the car. Had to turn car off for several seconds, then on again, now back to square one. I tried an OBDII reader too, just 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.
