Question about BMW 530
You may have a bad o2 sensor causing it to dump too much fuel into the system. I'm sure by now you checked all the plugs and wires to make sure they were o.k. Idon't know how many miles are on this car but when a catalytic converter goes bad it could cause this problem because the catalyst inside has fused into a solid exaust blockage and wont gasses escape the tailpipe. open up the exhaust and see if it runs normal after that.
