Just started after having no previous issues. Recent tune up. It misfires/runs rough in reverse and when put in park. In drive it runs perfectly fine. Any ideas?

Hey CHEEVA2006,

Have you got access to a scanner?

If so please scan for codes and let us know what you have.

If you have no misfire codes please carry out a power balance test.

When selecting P,N,R and D what happens to the power balance?

Do you also get the roughness in Neutral?

Do you get a reduction in power from any cylinders?

From what you have said it sounds more likely to be a motor/transmission mount issue than a misfire.

If you have no PCM codes and the power balance checks out ok i would say check for a bad motor/ transmission mount.

Any more questions don't hesitate to ask.

Let us know how you get on.

Regards, Joe
