Answer 1

Hi there,

The code is for multiple misfires. This can be the result of something simple like it needing a tune up, to low fuel pressure causing more then one cylinder to misfire. If it does it at idle it might be a problem with the intake manifold gasket leaking. Based on your symptoms, I suggest having the fuel pressure tested.
