Yr02 320 Auto Low Idle when warm triggers EML ligh
Hi guys, this is my first post so apologies if this is in the wrong forum. Hopefully someone can help.
I have a UK 2002 320 Coupe Automatic. The engine runs very sweetly but when it is warm (normal temp) after a journey I brake normally to stop at the traffic lights for example, still in Drive, the revs idle at about 0.6rpm, then after a while the revs drop down to 0.5 and below and this triggers the red oil light which in turn triggers the EML light to come on. I have had it plugged in at the garage and the codes say that there is a misfire on all cylinders which seems strange to me as the performance is fine and the engine runs fine until warm. Any ideas?? Thanks
