bad idle

[benzbiz]

hi all my 230e 123 does not idle properly when cold it revs at about 500 rpm
and when hot about 1000 to 1200 rpm how can i fix this problem:sad:

My E230 has a similar problem - I've just had a mobile tuning bloke out who says I should replace my exaust sensor.

You could also try your MAF sensor.

i don't think the 123 230e has got one of them

You do not have a MAF or EGR valve in a 123.

I will try later in the week to look up your faults in my Auto data injection manual, your is injection isnt it
