Hi,
In October I bought my daughter her first car which is a 2003 Micra 1.2S. With the help of posts from this club I have solved failed boot button, interior light and airbag warning light issues so thank you. However, my biggest headache is still not solved. Two weeks after purchase it developed issues on idle when cold with the revs rising and falling for a few minutes and then clearing. A local independent garage cleaned a reset the throttle body and for two weeks all was OK. Since then the problem has returned but isn't exactly the same. The car starts and runs (when warm) without issues apart from a tendency to lurch at low speed in any gear but if you press the accelerator it is fine. Performance and economy are good. When cold, after about two minutes the revs can rise to 1500 and fall to 600 rpm and although the car keeps running, there is a lot of smoke from the exhaust and the car runs rich. After a few minutes, and when the cold light has gone out, it clears, idles at 800 rpm and doesn't smoke. It has been back to the garage and they wired it up and although it doesn't show any fault codes, they see that the fuel management is erratic when cold and actually not 100% when warm. We are awaiting a final diagnosis but it is apparently pointing towards a main/engine ECU issue. If it is this then it looks like I have the following options:
1. Replace with a new one from Nissan at £560 ex VAT plus £105/r to fit and reprogram.
2. Buy a second hand one and try and get it reprogrammed
3. Get the old one fixed (but if they can't see an obvious fault I have been told that they won't be able to fix it)
I have taken some video bit no idea how to upload these.
My apologies for the long (first) post but does anyone have any suggestions please?
