RPM fluctuation at idle in drive or neutral? Just picked up a 94 Z28 but it has a RPM fluctuation at idle and while in drive, it will drop down then go back up every once in a while, otherwise off idle it runs great.
Any idea's?
Very much appreciate it.
Thanks

Mine used to do the same thing...drop about 100rpms then would pick back up. I had a very small vacuum leak. I also changed my plugs and wires at the same time. Not sure which fixed it but I am pretty sure it was the vacuum leak.
