my 1994 530 with an m60b30 has just failed emissions horribly
I recently purchased this car for a good deal and have been fixing it up here and there with my 95 540 parts car
Using a peake research code reader it was throwing four codes, lambda control 1, lambda control 2, O2 sensor 1, and O2 sensor 2
So far I have changed the spark plugs and coil boots, cleaned the ICV and MAF sensor, and have a ccv on its way in the mail and just bought a fuel filter which hasn't been put it in yet, and changed the crank sensor which is reading ohms in spec according to troubleshooting manual
at times it can idle a little rough specially when cold and when hammering on the gas at around 3500 to 4800 rpm it bucks and hesitates as if there were a misfire
I am new to owning a BMW so any help would be great, I thought about replacing o2 sensors but would like some advice before spending more money
