Default 99 century ignition problems

Ive been chasing an ignition problem for a while now, changed crankshaft sensor then coil packs all worked well for a while, then it wouldn't start in the mornings but it would in the afternoon. took it to a local shop they said they cleaned the icm, worked well again until last week, so i cleaned it again but it still was doing the same thing so i replaced with a new one and its still giving me problems, I've noticed tho that if i wiggle the wires on the one connector it'll start up. so i don't know how to go about fixing this, i cant seem to find the right part or wire harness for this, can anyone help? Its the one with 4 wires

Clean the ICM? How?
Look at the male and female pins for the connectors. See green?

Sounds like a damaged connector.

I bet it'* one of these:

Verify new plug exactly matched old plug before getting to work.

I recommend this be soldered on properly, not crimp-connected on.

If no green just close the pins.

You need to manipulate the pins with a pick tool to get them to have a tighter handshake.It'* called pin tension. How well they grab each other.
