Late last year my 2001 955i was ticking over like a bag of shit, very low and very uneven, I replaced the stepper and hoses and balanced the throttle boddies, the difference was amazing, but 7 months and 5k later its ticking over at around 800rpm, this time tho its not erratic its even, just low its not cutting out or stalling but should be around 1100, reckon the stepper might need setting upon tune ecu???? any input would be helpful.
Bring it round and i'll See what can do if I can remember!!
Well thanks to Chris the bike is now ticking over sweet around 1150 ish, small increase in stepper motor steps on tune ecu and it sounded better straight away, took it for a spin in some stop start traffic and then rode home and even when hot the tick over has remained level and steady, very pleased.
