My jeep 4.0 is getting a red spark instead of white I replaced the CPS and ohm it out its good just not getting the right color or even a lose wire? Sometimes when I'm working on it, it loses spark and I have to move some wires to the coil and gets spark again idk what do y'all think?

It's probably the terminals in the coil pigtail are opened up. With it running, wiggle the coil pigtail. Does it die? If so, use a pick to close up the terminals to make better electrical connection. Afterwards, check the connection with another wiggle test while running.
