I have 2004 lincoln Ls problems with codes p0171 p0174 p430 p2195 p2197

All the codes can be Googled and looked up on OBD11 sites. They tell you the fault and how to fix. There are videos as well

looks like its all emission stuff

PO171 & PO174 are codes for fuel too lean. So is the clattering valves when you step on it. Sounds like you got some bad gas. Try filling up with a high octane gas and add a gas treatment for Ethanol which will help get some water out of the system. Good Luck

P0171 & P0174 are lean codes.this can be cause by a vacuum leak. One of the symptoms is a ruff idle when cold.

You can listen for it or you can have it smoke checked by a shop. Most common causes are intake plenum gaskets and rotted PVC hoses.

My car did that once and I didn't have my gas cap on tight. Not the same model but worth trying.

• There are some clips on the back of the engine by the manifold that break real easy. In fact there is a TSB about them. These clips hold the IMRC linkage rods to the runner shafts. When they break the linkage will just hang there.
• See diagram

• These are a dealer only item. Replace them and this should fix your problem.
• Hope this helps and thank you for using FixYa.

Most likely a vacuum leak effecting the O2 Sensors

That is your 4 codes.

Have the Evap System checked also, for leaks

Fuel Filter--filters fuel,doesn't fix anything

Unless your familiar with the cars systems
and I assume your not.
You take it to a repair shop

I have a 2004 LS V8

You can not work on that veh yourself
if your not famialiar with both OBD2
Sytems and the Lincolon LS

If you have a specific few questions
I will answer them.

PO-430 Catalyst System Efficiency Below Threshold (Bank 2)
PO-0301 Should be a misfire on COP Coil #1
PO-316 Misfire Occured in the First 1000 Engine Revolutions
P-2195 Lack of HO2-11 Switch/Lean
P2197 Lack of HO2-21

I have the same vehicle,only a V8
What you have is a very common ford problem. The Ignition Coil on Cylinder #1 is Bad. You can buy it at the local auto part store and change yourself. About $59.00. You remove the coil cover on top of the valve covers,then the coil. I did one in Feb and believe all you need is a 7mm wrench and 7mm socket. #1 should be at the front of engine/pass side.

The other codes are related and you can see if any are there,after you do the coil replacement. If so give them to me.

Hi
171 system too lean
174 system too lean
2195 - 02 ozygen sensor signal stuck lean Bank1 Sensor 1
2197- 02 ozygen sensor signal stuck lean Bank 2
Sensor 1
The 2 front 02 sensors are located on the front of
the exhaust manifold.
Should solve problem and increase gas mileage.
