lean idle misfire
It happens randomly I changed my defective erg, has fairly new plugs & wires, new coil & icm, can't find any vacuum leaks, crappy gas?

wires would be my guess as well...
I once chased a misfire for weeks after a complete tune up. Ended up being the "new" wires that were installed. If the wires make the spark slow or weaken it with excessive resistance, it'll misfire.
