Engine Performance problem
1998 BMW 740 V8 Two Wheel Drive Automatic 285000 miles
I have a 1998 BMW 740iL with hijgh mileage. The idle is bad causing car to vibrate an it has a rich exhaust smell. Compression test reveals that all cylinders but one( number five is reading 150. But number 5 is reading 75. If this helps, the service engine light stays on constantly in yeloow and the asc/dsc light and abs light is on all the time.
Already replaced spark plugs.
