    Yup I have an 01 740 with a similar issue my problem is that it gives a hesitation on light to moderate acceleration but getting on the highway it doesnt give me the issue. anything above 2000 RPMs and the problem goes away. If your Check engine light is on scan the car with a scan tool. Be carefull when dealing with the fuel system because it can kill you..

    Bottom line your fuel filter is clogged, so yes you are right, and you have either damaged the fuel lines or the fuel pump, a common problem. before you have the fuel pump done by BMW and only by BMW because anyone else will screw it up by taking short cuts. either syphon the gas out so you have just enough to make it to the dealership or keep driving it until your are low on fuel and then take it to the dealership. This will reduce your labor time which will save you money because in order to get at the fuel pump they must remove the fuel tank and it takes forever to remove it when its filled with fuel and it is difficult because 20 gallons of fuel is anything but a light weight. Hope this helps.

Hesiates on starting & missing, the gear shift for drive there is a light that goes on while driving will not go off without turning off the engine. I ran the codes on it sometime ago and it said

Check your fuel pressure. Sometimes your fuel pump will give to much or to little fuel to the engine. Changing fuel pressure regulator will solve the problem. What is your RPM needle doing is it pulsating or going up or down...Please let me know so we can solve the problem.

It sounds like either the throttle position sensor or the mass airflow sensor are bad-the TPS can be checked with a digital meter, it should give different voltage readings as the throttle is opened with the engine off, key on. The MAF can be cleaned with MAF cleaner, or will need to be replaced. Another, although less likely possibility is a clogged fuel filter.

A clogged fuel filter can do it and a vehicle in need of a tune up. A vacuum leak in the engine or airways could cause shaking. You could have a bad fuel injector. If it has been awhile since you have had a tuneup, I would get one done. If you have, maybe change the filter. May need to check all your fluids also.

Car jerks sometimes while driving down the road also in the morning time acts like it wants to driving down the road.

Time to have the timing/tuning checked up. The fault is relative to a cold engine and can be due to poor fuel flow/delivery or poor electrics.
So the check up for replacement of suspected components like plug, filter, coil , HT wires fuel pressure must be made.

check the vacuum lines on the engine.sometimes these will crack or develop a small hole or break and it will **** too much air in the engine causing it to act that way.

Correct fuel pressure on the 5.7 in my 1999 gmc 3500 van?

Check the TPS. If you code the ECU there might be a P121 stored in the OBD2 port. If tere is no code the a cloged converter will be your best bet.
