EDIT: solutions. OBD-1 port was UNDER the back end of the FuseBox.
my rough/cold idle was a old/leaking "rubber cap" (aka Vacuum Leak)
from a bad vacuum-cap on one of the tubes immediately above the PCV-valve.
so, a 0.25 rubber cap has me running normal...
---original post:
I have a '93 Explorer/EB 2WD-auto-trans
inside, under the dash, in the middle, right on the "hump"
at the front/top edge of the carpet (directly under the ash-tray)
is a connector.
it is "affixed" not dangling, and is open and waiting for a connection...
it is where a OBD-1 connector might be if it was one...
it is a little smaller than the ODB-2 connector (I tried )
The popular "sticky" posting on reading codes/paper-clip does not display
the photos that are described...
my reason for asking... (oh this is gonna be embarrassing )...
is that I cannot find my OBD-1 connector under the hood
behind the fuse-box (power distributor box).
I have a blower-fan with connection and another cable
coming from the fuse-box into a thumb-size round connector
and then leading on to..(?) with a ground-wire connected to the body,
but nothing that is labeled 'EEC TEST', or any connector with a cap that
is waiting for some access.
I can take a photo tomorrow, in the daylight.
My older Chilton manual(#26688, p4-36) shows a location that looks to be
closer to the Ignition-Coil-(where spark plug wires huddle together).
--- I have a rough/cold idle problem and getting 'Chk Engine Light" (CEL ?)
... I disconnected the MAFS and it seems to idle fine...
... re-connect and the rpms idle down to stall.
I **thought** this meant that the MAF was failing, so I got one...
and I have the same rough/stall idle with the "new MAF" installed.
I had some small air-leaks in my (big air tube) from MAF to the Intake...
and patched them with some duct-tape to diagnose...
--- I've read several postings on "rough cold idle"...
and I'm not sure I understand the variety of symptoms/problems
as they each sound like my problem...
and now I can't even find my ODB-1 diagnostic connector to
read my "Blinking Codes".
I was hoping to just get the stored codes via a Paper-Clip
and getting the MIL (Malf Ind Lamp) to blink the codes on the dash.
Can someone kindly point my nose in the right direction..
or maybe to a YouTube-video that clarifies the location
thanks.
