Hello to everyone
I have an 85 528 BMW (with a 325 motor). It has been a joy to drive up until a month or so ago. It started idling a little rough, not bad and I started noticing the exhaust was really black and thick. Then it had a power loss..like trying to go up a hill in neutral..once it got going it would be fine...but it made me nervous to drive it out on the freeway. so I took it in to a mechanic and he replaced the spark plugs., dist. etc etc...ran a little better..but still no power pickup/backfiring..etc. I changed the fuel pressure regulator myself after reading many posts regarding running rich, etc...now, I try to start it and it cranks and cranks but wont turn over!!! I am VERY new this and I know a little bit here and there.....I am trying to figure this out on my own or try to get as much info I can...I dont want to get taken just because I am a silly little ole' female!!! haha... I have been told it may be the cold start valve..or the idle control unit...any advice, info..etc will be GREATLY appreciated. Thanks to all ahead of time..............kp
