1994 Mercury Grand Marque

I keep getting a code 189 (adaptive fuel limit reached, left side).


I have a new Fuel filter, Fuel Pressure Regulator, Throttle position
sensor, Vehical speed sensor, and Oxygen sensor left side.

Any clues?

Thanks in advance!

Re: 1994 Mercury Grand Marque

Plugs read fine, just changed them recently and all were nice and tan,
right rear a lil more crusty than the others, but color still good and
all were dry.

Yes there was one other symptom, but I thought unrelated: After car
sits for many hours (over night or in work parking lot), regardless if
outside temp is 50f or 90f,..... it coughs and sputters for about 3
city blocks, then clears up and runs near perfect. Very slight ruff
idle at stoplites after warmup, but absolutely no cough or sputter.

Does the cough and sputter thing every single time (after the long sit
only), and ALWAYS clears up within 3 citi blocks.

then the plug read confuses me a little.

otherwise was thinking leaky or plugged injectors.

MAF or ECT sensor?..

Re: 1994 Mercury Grand Marque

I think I would be looking for a vacuum leak. Maybe a hose that softens and
closes a bit after warming a bit. I went nutz looking for a similar code
once and finally found a split hose. New hose fixed it and a few other
things I had ignored, like slow A/C controls.

Re: 1994 Mercury Grand Marque

I had an old Crown Vic with 5 lliter EFI and an AOD that gave
persistent codes despite several rounds of troubleshooting. Eventually
it generated a code not on the list. I called my uncle and asked him
what it meant.

After looking around and asking his buddies in Dearborn, he finally
figured it meant to pull the EFI, ignition and computer out and put a
carb and a Mallory distributor on, cut out the catalytic conveter, and
get rid of the air pump. He must have been right because the car gave
many trouble free miles thereafter.

Re: 1994 Mercury Grand Marque

I had that code on a 93, replaced both ACT and ECT (both gave some odd
readings) and vehicle was fine. symptoms were rough starting but only in
cold weather and usually only when it was 10 deg F and colder. started great
and -15 below though...

Re: 1994 Mercury Grand Marque

Changed both the air temp sensor and engine coolant sensore this
morning.

I still get the code 189 (adaptive fuel limit reached, left side).
Driving me nuts!

No visual sign of weak vacuum lines.

I ran crappy fuel for a few months, perhaps some of my injectors are
dirty. Just completed a tank of quality fuel system cleaner and will
stick with BP 93 octane for a while and hope it clears up on it's own.

Totally lost here.

But I truly appreciate all the input from you folks! Thank you.

BTW: Seems to be running better, just keeps giving me that pesky code!

Re: 1994 Mercury Grand Marque

Reseated the connector plug on rightside (opposite side) oxy sensor,
filled up with BP 93. Short test ride, no code. Nice smooth idle.
(Code always said left side).

Knocking on wood, will know better tomorrow, after 40 mile round trip
to work.

The startup sputter I suspect is bleed back thru the fuel pump check
valve, and will stay with me, but if I can keep from getting codes
after warm-up, I shall be content.
