Idle and cold running issues

Johnno11 · 29-09-2015, 09:30 PM

Car is an S1 16v conversion.
Car runs really well when warm but for the first 2 mins from cold it starts fine and then bogs down at around 2k revs, so you have to change up or feather the clutch. Only does it for a couple of mins then it'll pull through it and run fine. It reminds me of cold 2 stroke bikes years ago. Any ideas?
Also, the tick over sticks at around 1500 rpm. Have replaced the ICV but no better. If I disconnect the battery it goes back to normal (900-1000) for about a week then starts doing it again. Could be same problem maybe or 2 different ones???

Thanks
