Does it have to have a OBD2 port?
I have a vibration that I think is a missing wheel weight on the Corolla, it doesn't even have OBD1 .

Noise,vibration and harshness. I had never heard of these terms until reading the brochure for a 1973 Cortina GT which I foolishly bought. In the brochure Ford claimed to have cured NVH, Even after a Cooper S, I wasn't even sure what NVH was, but it sounded good in the brochure.
After owning the POS for a week, I knew all about NVH. The Mark lll had an adjustable nose piece angle on the diff and a floppy centre bearing on the tail-shaft. You could adjust it to be smooth on acceleration or deceleration, but not both on he same setting. So after my Cortina experince I'm wary when people mention NVH.
