Acceptable Rough Running Values

[logray]

The 986 WSM states the following regarding warm idle rough running acceptable values. (unfortunately my copy of the wsm for the 996 is missing this data - the scan of that page is bad).

Rough running threshold be near 6.3.

Deviation +/- 1.5 (1/s squared)

Rough running shoudl be near 0.

Deviation +/- 1.5 (1/s squared)

Does anyone have the acceptable values from the DME for a 1999 996 3.4L?

This is related to timing correct? I can't find a good definition for rough running.

Thanks in advance.

72k miles. Here's what I logged in Durametric.

Digging this one up to ask if the same data is available for the 3.6l M96 in the 996?

Or are the values identical despite the longer stroke?

The manual does not list separate setpoints for 3.6 liter engine. I would expect them to be the same or very very close.

That's what I was thinking.

Thanks for the confirmation, Loren.
