Hi,
My first foray on this great site...
I recently bought a 1994 GS300. It runs well, and looks great (now it's had a major detail - I bought it at an auction).
I opened the hood and was pleased to see a big matel thing, which I take to be the engine. Good so far.
But I just noticed that the little black plastic "DIAGNOSIS" box is empty... What's that mean, then?!
Thanks,
Richard
