Weird RPM jump during acceleration, cant figure it out

[TweeT91109]

So when Im driving occasionally My motor likes to kinda hessitate while going there the RPM's. When it does it, and I come to a stop and idle, the RPM needle jumps around like crazy. Ill get back on it and eventually it figures stuff out and doesn't do it anymore. Here's a small video kinda showing you what i'm talking about....its happens a lot towards the ending of the video. Does anyone know what might be causing this awkward behavior?

Whats up with the temp gauge????

Loose ground, possible break in igt from ignitor to ecu. Did it just recently start?

Yeah it looks like a faulty connection somewhere at the rpm signal connection.

Probably a missing noise filter...

If this is a 7m motor, check the ground from the coilpacks. Check and make sure they are not cracked too.

OK will do...cause I thought the grounds that went bottom on the intake manifold, weren't making a good conection...so I put new eyelets on it and made sure the intake throttle body was making a good ground....well it fixed it for a bit then started acting up again....so Im thinking the harness right there might be moving and causing a break further in the harness.
