Re: MY 1991 740 TURBO SEEMS TO BE CLOGGED
Does not sound like a turbo lag or a boost issue. Might you want to check on your intake manifold or turbo in/out attachments specially the clamps for leaks. In some instances a defective (torn) air filter could also cause this.
Of course it would be best to consult an onsite qualified professional as it may have to do with your engine mapping.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

First, go to AutoZone, Big A or any chain autoparts store, most have free CEL code reading, that will tip you off in the right direction.
Sounds like you have a EVAP issue, and the fuel system is losing fuel pressure, so when you press the gas, you are calling for more fuel allowing it to pressurize faster. Instead on quickly turning the key on, turn it to ACC (Lights and chime) wait 5 sec, then try to start. Most cars will start the fuel pump and pressurize the system for a quick start.
Well your car is multi-port fuel injected, so it has a throttle body instead of a carb. Have you checked fuel pressure with a gauge to see if the fuel pump is working ? The pump or filter could be clogged up.
THe problem is that there is no fuel due to fuel dirty fuel filter. When you are at constant speed as 50 mph, you don't have to press gas pedal to much requiring instant fuel. However every time you need to press the pedal, you can experience this problem. Now it is really clogged up ,so fuel is not delivered to the fuel distributor so it can't start. Need to replace fuel filter.
Check the turbo and Turbo intake hose. I've got the same problem and it comes up with a broken turbo pipe leaking the pressure necessary to provide power. Possible is too the blocked air filter and/or fuel filter.
See...I could hear it from here!!! Sometimes its worth the time and $ to have a shop do that job....been in the business far longer than I probably should have been and still won't do that or a trans job in the yard unless it's a dire emergency. It's just so much faster and easier doing the job standing up!!!! Good luck with your car!!!!!
This sounds normal to me! The engine will read that rpm when accerlerating lightly. It is the stall of the torque convertor. The oil pressure will always be higher when the rpm's are higher, or when the oil is thicker - cold.
Virbration? That is a different story. Oil won't cause that.
