Stutter/heistation at low RPMs - ZR-1 Net Registry Forums

BigBiss · 06-05-2011

I had to change the alternator and now have a serious stutter at low RPMs even in neutral. The secondaries are kicking in, but stutter is there at low rpm in all gears. I did change some of the vacuum hoses at the same time, they seem tight, could this be the issue? I am showing no codes, so I am lost at this point. Is there something I missed during the alt change? Any thoughts or direction would be appreciated.
