Resolved What does this ground wire affect

What does this ground do? it is attached to the intake and the wire runs down into the ignition harness. I did an electric check and current does not pass through it, it is dead end to end. can I just run a normal wire without this piece or is the way it is required with the little barrel section on the end?

Are you sure it's a ground? It almost looks like it is the connector for the noise capacitor (aka filter) bolted on the intake manifold. See post 21 here: https://www.dsmtuners.com/threads/2g-dsm-engine-bay-electrical-connections.298047/

Yes you are correct i did a deep dive on it and eventually found out what it is. Thank you for replying. This is my first encounter with this particular part and was dumb founded on what it's function was. If mine is busted then is there somewhere i can get a good one?

Probably any auto store. The original capacitor is 0.20 uF, 25volt minimum (I would get 50v to handle spikes however) but any capacitance value around that will work. Just get one where the can (the negative side) can be bolted onto the manifold and make your own wire connector. The other end should connect to coil positive and should have had +12v on it with key on. So if yours didn't there must be an open connection. The capacitor reduces ignition noise in the radio and sharpens the coil primary falling pulse.

Could this being bad cause an intermittent misfire every now and then?

 

[luv2rallye]

No. It's very unlikely unless that wire is still connected in the harness to the coil and intermittently touching ground (bouncing around). But you said it's dead end to end.

 

[JeffGS-T97]

It is, im tracking down a few little issues that i want fixed and i wanted to eliminate that as a possibility, i didn't know if that wire being dead could cause adverse issues with the spark in the ignition system.

 

[luv2rallye]

If it's truely dead (not connected to the coil primary +12v) then it's not your problem.

I have worked on alot of cars and these engines have some really strange hookups and sensor functions I'm not used to. I still have alot to learn about on this platform.
