Default LS swap issues/air fuel

Just picked up an OBD1 swapped 92 eg sedan. It has an Autometer wideband that I believe may be hooked up to a stock O2 sensor. The wideband reads all the way 'lean' the guy told me it runs 'rich' either way its a rough start up but after that it idles fine, when you're driving it's obvious there's something going on.

Would tying the wideband/gauge into the stock O2 cause it to run like this or is this maybe an injector/fpr issue?

your gauge has nothing to do with it. but you do need to have the correct oem narrow band o2 sensor plugged into the engine harnss.
check your plugs. replace them.
and check fuel pressure.
any CELs?

To add to that, what ECU are you running? Is the ECU Chipped? You should be running an OBD1 P75 ECU.

Are you sure it isn't one of those cheap Autozone A/F guages, because they don't do anything but light up colorful lights.
