Shake vibration Problem Help!!!
 

Hello everybody

I have a problem with my 03 X5 , used to run great but started leaking oil and I replaced the valve cover gasket and after that the car started shaking at 35-50 mph and service engine soon light came on , took it with a BMW technician and he told me one of the fuel injector went bad. I guess he said injector number 7 , so I decide to replace all of them and the problem persist and i noticed got worse. he say also one of my ignition coils is bad and probably is causing the car to shake.

before to replace the injectors the car shook only when pressing gas but now it shakes at every stop i make

any help would be appreciate. thank you

Did he not check the code(s)? Sounds like this tech doesn't really know what he's doing, and just throwing parts at it.

Is your truck a I6 or V8? It sounds like you're describing a misfire of some sort. I would suggest seeking out a reputable indy in your area.

We can only help you to a point with the limited info you provided.

Well X5SND. the first time the problem appear , I took my car to autozone and the scan threw the code P0363 Misfire Detected - Fueling Disabled. then this technician told me he ran a more throughout scan at the Dealer and result told the Injector No 7 was failing

I made a little research about that code but I found that particular code may cover many parts like a ignition coil , spark plug or injector to name a few

My X5 is a 4.4i v8

any help would be greatly appreciate

thank u

Fuel pump!

Hello " Big J "

I'm my consideration I wouldn't consider the fuel pump as the culprit but I will check it today later on to see if is failing or not

Thanks everybody for the help , if someone can help with more info that would be greatly appreciate:D
