88 kc vg30i
I can't figure out for the life of me how to retrieve codes from my box. there is no screw to turn and when I turn it on it cycles through the modes as if it wants me to pick one but I don't know how. Help please.
thanks

the only reason I am doing this is because she smells like she's running a little rich and and kind of stumbling some times when I am accelerating but it just about quits when I stomp on it. not that I am in the habit of flooring it everywhere but sometimes I just want her to go. I digress.

Check out this page? Yours was made in '86?

Looks like you have a similar ECU box as my 4 banger. I'd be real careful with that toggle switch on the side.
