Accent less power and stalling

Hello again!
I've had my accent for 3ish months, had a problem with the neutral safety switch which @AUTOSPARK helped me fix. My latest issue is the car has no power. I had a misfire and changed the plugs, it was ok for a week then it started to accelerate lumpy and has cut out a few times. On idle it's fine, when I accelerate there is a noise which almost sounds like an old VW beetle.
Has anyone else had the same issue?
Thanks, BPD

Also, does anyone know what this does? I noticed the harness was brittle and broken so taped it up. ThanksIMG_20181030_124006378_HDR.jpegIMG_20181030_122734198_HDR.jpeg

It looks like the connector for the ignition coil condenser/capacitor....

Capacitor for he ignition. You will have problems if that is not fixed well. They tend to be problems for rf stuff but they interfere with signals from the TPMS as well as some of the signals for CKS and CMP, now wait before the flame suit is needed, these signals are fine from that rf but if the shielding has problems the signals can pick up rf that will interfere with the good signal quality and can cause the computer to see these as problems. They will start out setting codes and as the shielding get worse and the signal is more and more compromised it can cause rough engine, misfires and no starts, they can cause real weird problems with modules that are not grounded good as well. I'm talking about the metal cage. They are supposed to be like a Faraday cage.

Thank you! I've just had a quick online search, they're not very popular in Australia

Thank you for the information! It pretty much sums up what I'm experiencing, although starting and idle is no problem, only on acceleration, for now. I've looked online and on eBay, the only one on there is from the states. When I googled the part number it's quoting a lot of Kia parts. Also, it only comes up with the female part and not the male/spade, should it be all one part as the new wiring harness would join together. Do you know what the male end is called?
Thanks

Ps I'll post a picture of what I've found, it's the same as @AUTOSPARK postedScreenshot_20181102-185816.jpeg

So after a bit more searching it looks like the part the capacitor plugs into comes from the ignition coil, this is the other part of the harness I was trying to explain. Does that mean I need to change the capacitor AND ignition coil? Or if I get a coil from the scrappers can I pinch the harness off it and wire it up to mine? Thanks

You don't need to replace either of the parts.

Just buy new male & female crimp on connectors, cut the old connectors off, crimp the new connectors on...simples!

Look, here are 10 male-female pairs of $1.

And you might as well invest in the proper crimping tool for the job too since you'll be going all around the car looking to see where you can use the other 9 pairs of terminals

Thanks for that!
