: Hi, : For some odd reason, the engine in my 89 635 "sputters" at 2,000 rpms. It has alot of hesitation at the 2,000 rpm both speeding up and when I take my foot off of the gas pedal. It feels like the engine is not getting enough fuel at this rpm. Any suggestions? Do I need to do a major service? The car has 189,000 miles and was checked from head to toe at 181,000. : Thanks : JH
