Misfire that sometimes goes away under load

[E30CSWolf]

Hello all. I have a 1990 325i that’s missing at idle and sometime under load. But not always. I replaced the plugs, wires, distributor, rotor, coil, injectors, fpr, vacuum lines, and fuel filter. I’m not sure what’s next to check. Any advice and help would be appreciated

Check the connector under the intake. It's for the fuel injector harness and coolant temp sensors.. Sometimes you'll find some corrosion or loose pins..
