Hi all, my E30 is having running problems and I could do with a hand.
It idles and revs fine until warmed up, plenty of power available, then
once warm it starts to run rough, sometimes stalling at idle. The
exhaust becomes smokey at this point also, as if the mixture is far too
rich. Sounds like the choke isn't releasing once it's up to temp. The
ICV, throttle body and injectors have been cleaned through and new
plugs installed recently, no difference. Anyone had a similar
experience? Thinking of renewing all vacuum hoses as they're the
originals, and cleaning sensor connectors etc. Any idea what i should
try next? Is there any way to test for a faulty temp sensor or O2
sensor at home without bmw diagnostics kit?
Thanks very much!
