I'm trying to nail down why the check engine light keeps coming on on my '89 LX 5.0.
I took it to AutoZone and the guy there said that the wires were hooked up to the OBD1 port, like maybe the plastic piece had been removed and the wires were jammed back in in the wrong order.
Does anyone have the pinout for the OBD1 port? I just want to see if he's right or pulling my leg.
