My check engine light has been on for a few months. Originally when the issue began, a local auto shop machine said that it was oxygen sensors. I recently replaced two and it ran fine for a day. It seems fine when its started but when its in gear, it shakes, and it barely picks up any speed. There is also a burning smell. the second auto report stated that it now need as cam sensor and ignition coil.

Newest reported Ford Taurus problems
The engine may misfire and/or buck while driving at freeway speeds with no fault code stored in the powertrain control module (PCM). This can be caused by an intermittent fault with the camshaft synchronizer assembly. This condition can be diagnosed by monitoring knock sensor data as per Ford service bulletin #05-22-12. Replacement of the synchronizer assembly will be required to correct this concern.
The synchronizer shaft for the camshaft position sensor can cause a loud squeak or chirping noise due to failure of the upper bushing. The noise may be erratic and is usually present when the engine is warm.
Leaking antifreeze and I noticed it was coming from underneath the car in the back by the oil pan.
I lifted the car up on jackstands and realized it was a black metal pipe/ rubber hose combination which is crimped together with a silver piece of metal.
This assembly connects to the heater core against the firewall. I ordered the part on 1AAuto which also had the video procedure posted on youtube. I removed the passenger side cowl and the ...
A Lack of power, poor fuel economy, and black smoke from the exhaust can be caused by a defective MAP (manifold absolute pressure) sensor.
Worn motor mounts can cause the motor to rise during acceleration, causing a clunking noise and possibly damaging the AC hoses. Damage to the AC hoses can cause a loss refrigerant resulting in no cold air from the AC. The motor mount will need to be replaced prior to repairing the damaged hose or the problem will continue.
The magnet for the camshaft position sensor may fall out of its mount and damage the synchronizers. This causes long crank times when starting the engine and may cause the Check Engine Light to illuminate. If this happens, both the magnets and the synchronizers need to be replaced.
If you experience difficulty starting the engine when cold, stalling at idle, or hesitations during acceleration, it may be the idle air bypass valve. This valve helps the vehicle idle steady when the accelerator pedal is not pressed.
While steering, if you hear a clunk or a rattle, or if you experience premature tire wear, this could indicate the inner tie rod ends are loose or worn and will require replacement.
The engine oil pan gasket can develop a leak. Leaking oil may accumulate on the exhaust system resulting in a burning smell. Replacing the gasket should correct this leak.
broken valve spring. broke valve stem and destroyed piston.
replace engine with ford rebuilt long block.
code 340 and after replacing the cam sensor and sync assembly, the code still exists.
with all readings normal, scope pattern of the cam sensor are ok, the code remains due to a faulty DPFE triggering the code. Ford is aware of this issue and has no fix available for this issue.
care needs to be taken when diagnosing this issue as to not replace parts that are, in fact, still good.
We have tried re flashing the PCM with negative results.
when i turn the automatic light switch on my healghts dont come on but my running(parking) lights do
