i posted a thread a few months ago. I cant find it now. My 94 bmw 530i Went from 60mph to 20 and would not go any faster, unless I unpluged the MAF sensor, then I could go 60 mph the slow pickup. The only code was a oxigen sesor. The problem turned out to be the fuel pump. Now we no. Thanks to all that tryed to help.
