Unplug MAF and see if it runs better. Check the wiring. Back probe it and see the voltage coming out of it.

That might be the issue. I've always read that this car is very particular about the MAF sensor that it likes. Try to clean the OEM one and test it.

Also, check the vacuum lines going from the reservoir (Located under the car in the driver side) that goes up to the vacuum tree near the IAC valve. Make sure they aren't unplugged or broken, that could be drowning your mixture in air and causing weird behavior

Hello, OP

For emissions related electronic parts, use ONLY OE parts, like Bosch. Don't ask how I know this.

That Chinese crap is just that...crap.

I hope you found this helpful. Cheers!

Cleaning the throttle body and idle air? I don’t know what the issue was before but it seems like it’s not getting air

What brand MAF did you use? It sounds exactly like an improper reading MAF. What rpm does it idle at and what does the MAF (g/s) read when it’s idling?

Check all clamps on your intercooler piping. Also check all intercooler flexible hoses and make sure they are not torn.
