For the last few days when I turn the key to shut off the motor I feel a shake in thecar almost like if i lifted the clutch while the car was running and it stalled. I have started and shut off the car while on a lift and don't see it hit anything but it shake for about 3 seconds and then shuts down. anyone with a answer

 

check the timing and fuel system out?

 

I have changed the pump return and filter and it stopped for a few days but now its back less severe but still there.
What do you mean by check timing. I thought that was takin care of by the ECM?

 

add me in with the same diagnosis.,.. mine does that when i start it...kinda makes a bang sorta noise.

 

Sounds like its dieseling after shut off, I don't remember what the cause and correction is for that but I know someone will have a better answer or an assist to mine!!

 

btt?

 

I didn't think fuel injected engines could diesel. I guess if there's fuel leaking into the intakeit could.
