So i have a 1985 325e e30 2.7 I6 and i bought it from a guy that seemed a little iffy, but i bought it anyway because i wanted a challenge and it was a rare color. anyway ive replaced the intake manifold tested my fuel pumps relays and fuses. ive changed all the vacuum hoses and bought new fuel filter. but the idle is still sporadic. i cant keep it at a normal idle it will just go from 1000 rpms to 2500 and back down. almost dying. i've changed the idle air control but idk if the IAC motors were much better than the one i had on originally. is there any modules or relays, or anything that would cause this type of problem?
also would the iac motor cause the vehicle to dye as im driving and suddenly start up again or me having to turn it over again. it does this after 10 mins or so of driving.. Again anything will help:|:rock
I'm new to BMW's and just learning so anything could help. Thank you
