I own an 89’ 325i. It was running rich at start up and leaving black sooty deposits on the back of the car. Figured it needed a tune-up, cap, rotor, and sparkplug wires. A short time later I broke a rocker arm. I unassembled heads and noticed cam was badly scored. I decided to rebuild motor, used my 2.7crank Ross pistons, 272 cam complete head rebuild – larger 1mm exhaust valve, 19 lbs m30 injectors lightened flywheel balanced motor. I also noticed intake didn’t match head very well so I ported intake to match. Ran lean upper rpm, changed back to stock chip. Motor real hard to start and still black sooty deposits smells rich at startup black smoke. Changed coil msd blaster, cap and rotor runs stronger but no change. All parts spec out tps, 02, air bypass, crank pulse, cat don’t work also have m30 Afm to install. I have planed to upgrade to IE fuel regulator could this fix my cold and warm start problem. I believe it runs rich because i have to floor it to start it after many cranks it almost won’t run then it runs and smokes after its warm it runs great?
