Hi all! i'm hoping someone can help me troubleshoot. i've got a 91' e34 535i with an m30 engine. I was having problems with cutting power and not being able to accelerate since i bought the car. Every time i tried revving and bringing up the rpm's or even just getting them up in general use (merging onto the highway for example) it would totally cut all power and sputter and misfire until i slowly let onto the throttle and brought up the speed slowly.
First thing i did was replace the mass air flow sensor, helped but not much.
Then to solve the misfire i replaced the ignition system (plugs,wires,cap,rotor) which helped amazingly, now i can bring up rpm's and it doesn't short out.
But when i drive it its still puttering and noticeably losing power. i'm running low on ideas, patience and money!
Thanks in advance all!
