Engine Performance problem
1992 BMW 325 6 cyl Two Wheel Drive Automatic 132375 miles
i bought a 92 bmw 325is 4 weeks ago I replaced all spark plugs, mass air flow sensor (the old one didn't work) the idiot that previously owned it threw away stock air cleaner and replaced it with a regular open filter Has aftermarket exhaust wich sounds amazing and done right not a fart can I replaced intake manifold gasket and injector seals on all 6 inj.S ( The last 1 closist to firewall was leaking thats why ireplaced the seals the intake manifold has alot of oil like residue in it after I replaced the gasket and injector seals I used bg throttle body cleaner to clean but dont know if I helped the situation or broke loose alot of residue engine is sucking it up, I sprayed it through the throttle plate while running at 2000 rpm . Nyway its not leaking gas from of the injectors anymore runs better but still bogging at idle slightly and from idle to 1500 or 2000 rpm it sputters and backfires from exhaust and pops rarely from engine only happens when reving up or taking off until 2000 rpm then after that drives great if I take off slow it may sputter a little but thats it dont know what to do dont have $600 to spend on six injectors or the patience of saving up but hopefully you have an idea of what I should do, oh I have two or more coil packs that look like they were replaced and there is a little line of oil around sparkplug in two cylinders dont no if that cause whats going on I also replaced air filter will send pictures of engine if u think will help
