Question about 1983 Chrysler Cordoba

1 Answer

Poor mileage, runs rich, fails smog

My 1985 F-150 failed smog, CO very high. I suspect the feedback control solenoid, but you can't buy one from a Ford dealer or Autozone. Nothing online either. The local junk yards don't keep that kind of stuff around.

I already replaced the oxygen sensor, installed new manifold gaskets, and fixed some other possible exhaust leaks and a jammed plenum type gadget between the intake and exhaust manifold (it's a very strange design!)

The smog mechanic said replace the carburetor, but I already did that and the new one came with no feedback solenoid. So I had to install the old one on the new carburetor.

I have no options but to junk the thing, but it's a 4x4 supercab long bed, really useful for hauling junk around and going four wheeling in the desert.

As it uses a carburettor, set the main jet adjustment to run leaner.

SOURCE: 2003 T&C Solenoid Pack leaks

Depends on where the leak is from,the top or the side with the torx screws,if it's at the top which is usually the problem the gasket is about 5.00 and you have to remove the breather assembly,and the 3 bolts from the top side and wire harness from pack has a 10mm nut holding the harness on,install new gasket,if you remove the torx screws there are 3 springs,cups,and spacers that will fall out so the spacers go into the screw holes and the 3 springs and cans are all the same size so order doesn't matter on these.

SOURCE: Hard start when cold, running rich, poor fuel economy

Chrysler has a bulletin out for a simular condititon that involves replacing the pcm. Heres the bulletin number 18-005-04. This is only 1 possible cause , Fuel pressure, coolant temp sensor, thottle position sensor all can cause like problems. Seeing sensor values and fuel adaptives with a scan tool helps pin point problems.

Check for

vacuum leaks on intake manifold,

the air tube between the air filter.

intake manifold vacuum hose.

===
clean throttle plate with Berryman carburator cleaner

SEE sample picture HERE
===

Also remove carbon built up behind the EGR valve and the EGR passage tube.

===

Vacuum leak WILL offset the intended 14.7 to 1 air fuel ratio.

More un-metered air (leaks) will lean out the fuel mixture.

Use small amount of Berryman carb clearer at potential air leak area will help you identify trouble spot.

At idle,just spray and listen for the RPM surge.

The in-rush of carb clearer will increase the RPM on the motor.

Record the problem spot(s) and address it later.

===

EGR carbon built up require 2+ hours to clean from start to finish.

You will need a new EGR base gasket before your start.

Locate and remove the EGR valve after the vehicle is cool down.

Carefully record the connector and vacuum line (for older vehicle) location by drawing an easily to follow diagram.

Remove the EGR valve.

Inspect the location of the carbon built-up inside the valve and the EGR passage tube.

SOAK these areas with WD-40 spary.

You will need a small screwdriver,cloth hanger and lot of newspaper and time to get this cleaning done right.

RE-SOAK the carbon and let it sit for over-night will also help.

One the last round,pass a shop vacuum of the EGR valve and the passage pipe.

Install the new EGR gasket and connectors.

Allow the vehicle to warm up outdoor to burn up any remaining WD-40.


Take it for a test drive.


Please rate my answer if it's useful to you.

What causes too much co in youre exhuast


If you have a fuel sensor check that out. Could need replacing. Also when was the last time you changed the air cleaner filter. A dirty air filter will cause that as well as it can't breath properly. Just some ideas.

Runs rich


How can you fail more than once?

After you fail, you go to a repair shop &
resolve ALL Vehicle issues

Then the shop road tests until all 8 I/M Monitors
run clear ,or there is no reason to go back to inspection
knowing your going to fail.

The problem is the shops & peoples inability to explain
what they need taken care of.

If you never work on the vehicle for years,then you don't
go to inspection,it is a given you will fail

Spark Plugs-every 3 years
Check for Cylinder Misfires
Always install a New Air Filter before inspection
Always install new fresh full sys oil before inspection

Oxygen Senors get replaced every 100,000 miles

Have to road test with professional scan tool & look at
all data,check monitors,fuel trim,O2 etc & check for codes

You have to spend the money to evaluate the vehicle, to see
if it is ready to go for inspection,not many are,their just driven
& neglected

Rich could be-- O2 Sensors,Dirty MAF Sensor,Vacuum Leaks,
Injector Leaks & more,I have seen a dirty air filter fail a car

2004 2.0 lt. running very rich


on CO cars, it's below the ECU/PCM
but if you have lambda's, then its not a CO car.
CO cars are missing 02 sensors.
and you said, Sensors, as Plural. got 2?
you failed to post where car is and where it was sold new.
Or VIN.
Engine controls vary by country.
this car may be OEBD type ECU/PCM , "use a scan tool"
and if motor is rich , that can be for 2 reasons.
ENGine is rich
Catalysis dead, or both.
and CO is not HC.
but high CO usually does, give you high CO.

1986 NISSAN 300ZX FAILED EMISSIONS HIGH CO


I would replace CATalitic converter, this car is old, plus a tuneup is 100% necessary , spark plugs wires, ditributor cap & rotor, plus both the air & fuel filters need replaced. change oil & filter. then you will pass emissions test. and your car will run like its suppose too. if you don't do all this , then buy a new car !

1987 Dodge Caravan getting poor gas milage


If you suddenly are getting poor gas mileage your O2 (oxygen) sensor may have failed. The O2 sensor helps dictate how rich or lean the fuel mixture is. If it fails the engine's computer defaults to a rich mixture so not to burn a valve or run too hit. This can be checked and if need be easily replaced. And yes if the van is over-do for a routine tune-up this is always a good investment. Make sure to check the air filter too, if she's dirty the engine will starve for air and get poor mileage.

I hope this may have assited you,
Tom

02 kia fail smog high nox


if the engine computer says that you have a slow O2 sensor what it means is that the sensor does not react as quickly as it should and it needs to be replaced. nox is oxides of nitrogen, a product of too lean combustion which causes cylinder temps to go too high. it sounds like replacing O2 sensor will make it happy. engine computer is having a hard time controlling lean/ rich fuel mix because sensor is slow to register changes, needs to have response time in milliseconds or engine computer can't operate properly. O2 sensors do wear out, normal service item. hope that helps

1991 Honda Accord LX failed emission test on smog test. High CO and HC on 25mph


not enough info. Typically, CO and HC together can be the result of poor fuel control or misfire, or worn components such as O2 sensor or catalytic converter, but without more data, repair recommendations are likely to waste money and not achieve success.
