I’ve searched up and down and nothing seems to work. Trust me I’ve done EVERYTHING and am still trying to do more.

I just got a Mazda Reman installed and it has 1k miles pretty much exactly. It ran fine and all good till I gave her a few redlines and now my problem starts.

Car is idling super rough, it’ll dip under 500 back up jumble fumble then all by itself it’ll idle fine. Until I give it gas or come to a light then the process repeats. Idles funk then fixed by itself.

Also when letting clutch out in first it’ll shudder BAD. No matter how many revs I give it. In reverse same deal. Rowing through gears is fine though.

I’ve replaced coils, plugs, wires. Got a new MAF, had my rotary specialist check for vacuum leaks & nothing. I kind of want to replace the front 02 sensor but decided to take a break and try here for suggestions.
What could be wrong? I hope it’s not the engine but I don’t see why as it’s so early into it’s life & it starts up hot or cold perfectly every time.

I was doing some digging and took this photo:


Intake manifold near 3 solenoids, behind engine closer to firewall. Stuck phone in between to see.

Is this proper?

I’ll try anything & keep you guys updated till solution is found. Thank you in advance and I hope I can figure this out soon.
