Glad to have found this board. I have a 1980 320i 4 cyl. and a 1980 320i 6 cyl. Im having problems with my 320i 4 cyl fuel injection dist. It's so bad that my 4th cyl doesn't fire. Ive checked for spark like four time's just to be sure. The only way ive got the 4th cyl to fire is to change the fuel line's at the fuel dist.I did tried fuel injection cleaner; no luck the fuel dist. was replaced with a used one 10 months ago also the fuel reg. is new,new filter and coil's. does anybody know where to go from here.Thank's in advants.
