when accelerate the whole car start to shake. Car has 160000km on engine. recently changed all six spark plugs and three coils in the back. still have the same problem. motor also has a weird rhythm "shaking" . Don't know what's wrong with it please help. any advise would help. thank you

 

Need more info than the car is shaking. Do you have a check engine light on? Can you post a video? Does this happen when the car is idle? Does it happen when the car is parked with the gas pedal pressed? Did this occur prior to spark plug and coil pack replacement? What else have you done to remedy this particular problem? What other things have you done to the car since this started to include gas type, tire change, brakes, etc. No matter how small you might think it is, you should post it.

Ohh and welcome to the org.

 

Problem fixed.. Found out cylinder 1 has a misfire because the injector was clogged. So I took it out and serviced it.. Now the maxima is running at 100% again.. Thanks for the help appreciated
