Former Autothority MAF 3.2 Carrera user here.

Garbage, along with that dumb cone filter thing. Stomp on the throttle and you'd get a whistle out of the engine bay. Take the cap off the oil tank, no difference in idle. Thing was creating a vacuum leak (i.e. lean condition) somehow.

The PO at least had the decency to retain the original chip he had taken out of the DME. I tracked down a stock airbox and AFM on this site for a few hundred dollars. Those, a couple brackets, gaskets, rubber buffers, swap the chip back, and all is right with the world. Runs way better as a stock setup.

I tried to sell the Autothority setup on here. Shockingly, no one wanted it.

I just saw an airbox up for sale on here recently. Put out a WTB on the AFM if you want one.

BTW - you said you checked the coil. Did you check it while it was hot (i.e. during the poor engine running condition) or at room temp? For as garbage as that Autothority thing is, I never had the driveability issues you suffer.
