Question about BMW 530

1 Answer

Ok so my BMW is having acceleration problems. I think that it has to be something with the fuel system. Maybe fuel injector, or the fuel pump. We changed the fuel pump, and the car was still not accelerating right. It would go then it would stall. So then I tried the fuel filter and was still acting weird. Now the oil is starting to smell like gas. What is the problem. And how do I fix it?

You may have a bad o2 sensor causing it to dump too much fuel into the system. I'm sure by now you checked all the plugs and wires to make sure they were o.k. Idon't know how many miles are on this car but when a catalytic converter goes bad it could cause this problem because the catalyst inside has fused into a solid exaust blockage and wont gasses escape the tailpipe. open up the exhaust and see if it runs normal after that.

3.9 engine is idling rough but smooth when accelerating or driving. If I put in neutral it's still rough. Have 250000 thinking maybe injectors? Or where do I start?

Take an have diagnostics run . Could be a vacuum leak , mass air flow sensor problem , If fuel injector's where the problem it wouldn't smooth out while accelerating > Have fuel trims check , O2sensors . EGR valve stuck open a little . If the check engine light was on an had a random misfire code P0300 could be fuel injector. or a specific cylinder misfire.

My 2006 freelander (2000lt BMW moter) very high diesel consumption. You can smell it and lots of smoke (white and darker) please help. where do i adjast the pump.

One or more of the new injectors may be bad and delivering too much fuel. I don't think adjusting the pump is something that can be done without expert knowledge and tools.

My 2001 Chevy 1500 5.3 liter z71 has been giving problems accelerating if I press the gas softly it will slowly accelerate but after a while it will not climb hills and will sputter and bog ? I've replaced...

Sounds like the engine is being starved of fuel - most common cause is a failing fuel pump or a restriction in the fuel line, but could also be something else (like the fuel pressure regulator).
