I have a URD MAF in my 06 Tacoma. When I key up my 100 watt VHF radio, the engine stalls.
If I hold the URF MAF in my hand (while installed to the truck), the engine will literally respond to its physical movement IE: while I'm transmitting my 100 watt radio, if I'm holding the MAF in my left hand, the engine will drop idle to a shuddering 500rpm, if I switch it to right hand, it will stall. (while sitting in the passenger seat)
I will make a video showing this as soon as I can.
