I noticed this morning on my way to work that my car was shuddering for no apparent reason. I noticed it whilst waiting at various lights. It seems to tremble for a second or so then stop then start again a couple seconds later etc. Once at work, in park at idle i noticed my cars rev range would go up to half a 'k' after each shudder. The fuel light has just come on when i arrived at work and it rained last night. Im not sure low fuel would promote this issue but is it possible the rain has had some effect on my car? It seems to drive normaly and this has never happened before. It is a new car with 1000miles on the clock.

 

So is my wife...gotta' go!

 

Possibly Bad Gas?

 

Low fuel pressure / low tank will really wig out a FI engine, never let it get low, Iam conservative and to me 1/4 tank is park it or fill time. WOODY

Just had that with an employee and his truck.....

Woody, ENJOY

 

Sometimes mine will run like that a few secs after starting up b/c of my gimpy fuel pump / check valve.

 

No, she has a very healthy diet.

 

Sounds more like the right answer. Mine did that before I had the fuel pump replaced. Except it only did it after the hard start for a few seconds.

 

I wouldnt have the first idea how to check a valve and what it even looks like! After work i will see if it has the same problem, if so is it unwise to keep driving the car? Thanks in advance

 

Is your car under warranty? That's the easiest way to get it fixed. The check valve has to do with building pressure and keeping it there so the fuel is always in the lines. If it lets the pressure go then the car doesn't start immediately and feels like fuel is running out causing the tremble. At least with mine, maybe you are having a different issue.

 

My car started fine but i will put that to the test when im going home. Is it advised that i dont drive the car until i take it for a service? I do have a 3 year warranty. My car is due to get its first service done monday week. I also hope the cause has nothing to do with me driving my car relatively hard with a unused amg engine..

 

Why exactly would you drive it hard before the engine is even broken in??

 

Break in is historic and not needed, they are better machined, Always run it like you are going to drive it expecially if there is a warranty covering it, shake the infant mortality issues out early..........

Weekend Woody, yippie
