Hi folks,

My 1991 740 (B200F) has recently had a new (but admittedly not Volvo) exhaust fitted, from the catalytic converter back. Ever since, the idle has been rough. The best way I can think of describing it would be 'gritty'. The speed also fluctuates very slightly. The OBD tells me that I have code 2-3-2. I don't mind living with it, but if I can fix it it would make me very happy again!

Does anyone have any thoughts about what I should check/replace?

Many thanks,
John.
