can anyone please help?? its a 1988 535i, it was running fine then slowly started to bog down as i was driving, when i got it home it would idle fine but as you gave it gas it would bog. after awhile of doing this it would die when you gave it gas. now it wont start at all. it "kicks" like it wants to start but won't. i have new plugs, cap, and rotor. still nothing, i had to coil tested and it is still good. somone said the fuel filter might be clogged, so i took it out and put a piece of pipe in its place. still nothing. i was told if the fuel pressure regulator was bad it would still run and have black smoke (it never smoked). any ideas? cam timing sensor? clogged injectors? throttle position sensor?
