I am new to e30 so I get a bit lost sometimes when it comes to engine work. I have a problem with the idling of my m40. I have to no problem starting it but the moment it starts the idling starts to stall just above 1100rpm and will sometimes return to normal idling as soon has car becomes hot. I have also noticed that engine stalling returns when clutch is applied and disappears when clutch is released. I've heard that some guys tweak the AFM
Please could someone assist
