Re: [Chrysler300] popping

[ronbo97@xxxx]

Hi John -

Here's some possible help with the diagnostic.

Put the front of the car up on jack stands. The car need 
not be running. Turn the wheel to the left and have 
someone else watch to see what is happening, possibly 
from below. Is a flexible fuel line getting crimped when 
the wheels are turned ? 

Is there an electric fuel pump involved ? Also, does 
this happen *every time* you make a left hand turn and 
apply gas, or is it an intermittent problem ? What 
happens when you make a left and don't apply gas ?
