Was cleaning my MAF today and put it all back together and after it had trouble idling. Wouldn't go over 2500 RPMs. So I went back an noticed if I wiggle my wiring harness around it has trouble idling. What would be the best route to take on this? I have no experience doing any harness swaps, or putting a new one in. Think if I bought a new maf pigtail/plug and just rewire it that would work?

Let me know what you guys think
Thank you

If it won't go over 2500 RPMS, it's the MAF. Since it worked before, likely wiring.

You need to determine where the break is in the wires. Is it right at the plug? You may need to get a razor blade and peel back the loom and look at the wires to see where the problem is, then just replace the broken section.

If it is broken at the plug, then yeah get a pigtail and wire it up!

yea I wiggled it around and it fixed the 2500 rpm problem. I have yet to take it a part. Need a full day that I know I won't be doing any driving haha. Its the wires leading into the pigtail plug. Should be easy to fix (i hope) never done splicing or any rewiring but was watching a few videos.

Should be an easy fix! You can see the wires pulling out of the pins inside the plastic connector in your video. Get a new maf pigtail, and splice it into your harness. Make sure you solder it and heat shrink it.
Good Luck
