i have an early 850 2.5 20v 1992, which uses the Bosch LH-3.2 system. i find the car has a tendancy to cycle its idle speed up and down by about 60 rpm, it also seems to misfire at about 2500 rpm to the extent you can hear a small break in the exhaust note every second or so. i also find the car quite thirsty, any ideas?

p.s. checked all the on board diagnostics no error codes found.
