Question about Cars & Trucks
Town Car had a random engine misfiring. Changed plugs and got error code 2197. car sounds like a sawing machine and I can smile gasoline odor from Engine compartment. Should go to dealer or who can fix this best, and how.
The gas smell should resolve itself when you get the O2 sensor changed or find the cause for the lean condition. What is happening with the gas smell is the system is trying to add gas to solve the lean condition
There are many ways to look at this. Since 1 cylinder has not been blamed for the problem, the O2 sensor averages the exhaust to determine rich and lean mixtures. If extra air is seeping into the exhaust either after the combustion(exhaust manifold) or before combustion(Intake manifold) the resulting exhaust will contain more air in the mix and be classified as "Lean".
Your engine may have different features depending on the Year, Model, and engine size, v-6 or v-8. There are air venting devices in the Intake Manifold that may be the cause of the problems too.
These parts are the ISC solenoid and the Manifold Runners. Modern Intake manifolds have 2 chambers with the runners changing the chambers. If the runners are dirty, they can stick. One chamber can provide more air than the other and it will cause an imbalance, misfire, and incorrect fuelmix.
There are operating PODs which can work by Vacuum or Electric and they can become inoperative or unattached and fail to move the Manifold runner. These smaller parts are less expensive than the runners and could be all you need. Sometimes the plastic clips attaching the PODs to the runners breaks.
The people who see the most Lincolns to work on are usually Lincoln or Ford dealers. This does not mean a Private garage can not do a competent repair for a lower price. Sometimes Ford parts are cheaper and interchangeable with Lincoln.
It may be worth it to just change the O2 sensor to see if it is accurate or not. Then if the problem goes away, you have saved a big repair bill.

I have a ford 2003 windstar that was running very rough when cold and almost stalling. engine light came on. went to autozone and they read the codes for free and told me it was running lean on Bank 2 also. i came home searched for the O2 front sensors online using the info autozone gave me. there are 2 front sensors on my car that need to be replaced at the same time. look for ones that have a direct plug in and don't need wire splicing. the ones without the wiring harness are cheaper but more of a pain, i think.
they were fairly easy to replace. getting access with the wrench was the worst. reset the light by disconnecting the battery for a few minutes. seems fine now and the light hasn't come back on.

I think you will find the aftermarket Cat Conv. is the source of your problem, but without hooking up to the factory test equipment at my disposal at my Ford dealer this at best and educated guess based on 20 years of emission related work, I am a Ford certified master electronics technician

P0172 - System Too Rich (Bank 1)
Basically this means that an oxygen sensor in bank 1 detected a rich condition (too little oxygen in the exhaust). On V6/V8/V10 engines, Bank 1 is the side of the engine that has cylinder #1.
Note: This DTC is very similar to P0175, and in fact your vehicle may show both codes at the same time.
Symptoms: You will more than likely not notice any drivability problems, although there may be symptoms such as a misfire. This is the next code explained.
Causes: A code P0172 may mean that one or more of the following has happened:
* The MAF (Mass Air Flow) Sensor is dirty or faulty. Note: The use of "oiled" air filters can cause the MAF to become dirty if the filter is over-oiled. There is also an issue with some vehicles where the MAF sensors leak the silicone potting material used to protect the circuitry.
* There could be a vacuum leak.
* There could be a fuel pressure or delivery problem
Possible solutions include:
* Inspect all vacuum and PCV hoses, replace if necessary
* Cleanthe MAF sensor. Consult your service manual for it's location if you need help. I find it's best to take it off and spray it with electronics cleaner or brake cleaner. Make sure you are careful not to damage the MAF sensor, and make sure it's dry before reinstalling
* Inspect fuel lines for cracks, leaks, or pinches
* Check the fuel pressure at the fuel rail
* Check the fuel injectors, they may be dirty. Use fuel injector cleaner or get them professionally cleaned/replaced.
* Check for an exhaust leak before the first oxygen sensor (this is unlikely to cause the problem, but it is possible)
P0301 - Cylinder 1 One Misfire Detected
A P0301 code means that the the car's computer has detected that one of the engine's cylinders is not firing properly. In this case it's cylinder #1.
Symptoms may include:
* the engine may be harder to start
* the engine may stumble / stumble, and/or hesitate
* other symptoms may also be present
Causes: A code P0301 may mean that one or more of the following has happened:
* Faulty spark plug or wire
* Faulty coil (pack)
* Faulty oxygen sensor(s)
* Faulty fuel injector
* Burned exhaust valve
* Faulty catalytic converter(s)
* Running out of fuel
* Poor compression
* Defective computer
* If there are no symptoms, the simplest thing to do is to reset the code and see if it comes back.
* If there are symptoms such as the engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wires, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). In some cases, the catalytic converter has gone bad. If you smell rotten eggs in the exhaust, your cat converter needs to be replaced. I've also heard in other cases the problems were faulty fuel injectors.
Keep in mind that the "misfiring" are not only for bad O2 sensors, check the other componentes that I tell you before.
Keep us updated.

There are few possibilities that can cause engine misfire
issues. It can be issue with spark plugs or faulty spark plugs. Also get the
compression test done for cylinders. If any of cylinder shows low compression
then required, then that particular cylinder will cause misfire.
Also get obd codes scanned, the error code will let you know
which cylinder is misfiring or all cylinders are misfiring.
For your trouble shooting I suggest you to refer the help
