Intermittent SES - ZR-1 Net Registry Forums

You're right. The SC8 is for the Stock ZR-1 3.45 rear end. I thought that was what you were talking about. Sorry.

My experiance with an intermittant SES light that goes out than comes back on during decel is a vac leak. I have had this happen three times, the first I rebuilt the entire secondary vac system, then a bad out of the box secondary solenoid and finally with a bad out of the box secondary actuator. I rebuilt my entire secondary system and after I replaced the above "New parts" it has performed without a hitch.

From what I understand, when a VSS goes bad the car will not operate above 3K rpm. Just enough to limp home!
