Won't stay running. Why? Coil? Fuel filters? Where are fuel filters? on 1993 BMW 740i

Vehicle starts but dies unless accelerator feathered. In gear, barely moves when accelerator pumped vigorously. Will occasionally develop rpm's but rapidly deteriorates.

It's above the passenger rear axle under the car. For loss of power I would check and verify fuel pressure and volume, check for exhaust restriction. Autozone have some popular workshop manuals for free on line once you register (for free) on their website There is a company that independent auto repair shops get their information from, this same information is available inexpensively for people that work on their own cars.. The information is year make and model specific, covering repair procedures, torque specifications, fluid capacities and specifications, service bulletins, component locations, wiring diagrams ect.... Alldata is very easy to navigate
