IT DOES NOT NEED ADJUSTMENT! Unless someone has already been 'adjusting' things, in which case, these need to be returned to the factory settings.
You have one or more faults, which need sorting. When that is done, the misfire will be gone and it will not be over fuelling, with all the adjustments as they were set at the factory.
Can't help any further at the moment, since you've given us no clue as to what model and age of E30 you have, but testing the engine coolant (blue) sensor AT THE ECU PLUG will probably be the first move.
