I've been chasing a poor running condition and have searched the archives. Any help (or point me to a thread that applies) would be great. I've had an 88 328 for 8 mos, 50K miles when I got it, 53K now. I have a great independent tech who is just too busy lately to help. When I first took delivery, he mentioned that he noticed a slight off-idle hesitation. He replaced a few plug extenders, I took it, and all was well. I drove it almost everyday for 6 mos. For the first few months, at cold start-up, RPMs would dip before going into high idle. Then about once a month it would not high idle. I would drive it very low on power with clicking from the fuel relay. It would go away after several minutes and run all day without further problems. This problem became weekly, then daily, which has made it undriveable. I have traced it to the entire front bank not firing (using a timing light), testing the individual leads plus the coil lead. It smells rich, so that makes sense. I switched coils, and it runs well. Thinking that it was a matter of poor connections, I returned the coils to their original positions and the poor running returns. It seems to me that all components are working, just that the combination of certain components together do not. I am mechanically inclined, enjoy doing the work, just don't have much time to go down the wrong path. Would greatly appreciate some advice. Thanks.
