Rough Idle?

Posted July 2, 20195 yr

comment_578847

I noticed that my 77 Z is idling a bit rough. It used to idle at around 1100rpm but usually floats around 900rpm.

The air come from the exhaust isn’t steady when idling. It feels as if air is coming through and pauses every second or so.

i have uploaded a video to try to document my issue.
