Sluggish acceleration on my 2003 520

When was the last time you had a tune-up?

Hi John, The oil pressure warning light is indicating pressure not level. You say the warning light is on at all times and the engine is losing power? I believe you should have a compression test carried out on the vehicle. It seems highly possible there has been severe damage to the engine. Is the engine emitting any strange sounds? How long has the oil light been on? How often do you service the vehicle by replacing all filters and engine oil? What engine oil do you use? Regards John

Of course your car is sluggish, cylinder number one is misfiring, that is why the flashing check engine light, if you continue to drive this car this way you risk the exhayst system overheating and starting a fire. Ge the car tested for the cause of the misfire asap.

Hi dennis,

It sounds like you have a malfunctioning oil level sensor. Even with the oil level correct, if the oil warning indicator comes on after starting, the sensor is reading incorrectly. I would recommend replacing the sensor with your next oil service. As far as the sluggishness, the sensor operation will not affect that. I suspect that is a different issue.

check the accelerator cable it must be weak or worn out.due to which car starts sluggish while acceleration. -------- as you have replaced the most possible option/possibilities for car starting sluggish while accelaration its advisable that you need to get the codes checked at the car diagnosis center.so it will locate and confirm the exact faulty part. at www.autozone.com its free to get car diagnosed.they also sell parts if required after checking the codes. This will help. Thanks please keep updated. please dorate the solution positively .thank you for using fixya.

goto walmart and get wynn's signature engine tuneup(8$) and put in your engine and run for 100 kms then have a oil change see the difference.

check to make sure your oil cap is on and make sure your oil filter is on. let it sit in a driveway or parking spot put oil in it and let it run for a while look underneath to see if there are oil spills, then contact your local mechanic.

check the fuel filter and when was the last time you had a tranny service done and a tune up also check the drivebelt

You need to do a compression test on the engine cylinders. It appears one of the cylinders is not firing and dragging the rest of the engine down in power. The compression test will show if one of the cylinders has a problem.
