What was the code? P-0171? If so, you may have a very dirty Mass Air Flow Sensor. This is held onto the intake tube by 2 small screws. Take it out & look down inside it. You will see a couple of silever wires. Are they fuzzy-looking? If so, clean them with some brake cleaner spray. Reinstall, and check for a dirty air filter. Hope this helps

The car is shaking at 40 to 50 km/h and 90 to 100 km/h

that shaking is misfire,
the engine can in fact do that for 50 reasons.
there are 3 basic tests to find which path.
bad engine tests. (compression)
bad spark (ever tune it up in last 9 years?)
bad fueling, (too much or too little) lots of tests. to find this.....ask

1157 is lean (lean misfire is results) Oxy sensor railed lean.
Id work this first.
Id also reset the ecu, (scan tool) and drive 20 miles see if all these come back.

My 98 Buick LeSabre is spitting & sputtering. Seems like it is choking and coughing. There are some popping sounds & a smell that is different than straight gasoline. When it first started doing this,...

Before you said you didn't want to put $ into a new oxy sensor, I was thinking that was the problem. Vacuum hoses may be a part of it, but I am not too familiar with them causing the kind of sputtering you are talking about. When did the change occur? It may be a fuel pump, but it sounds complicated enough to have a real mechanic look at it.

Doesn't sound like you would know how to do a fuel pump pressure an flow testing , suggest you take your vehicle to a qualified repair shop that has the proper diagnostic testing equipment .
Rather then guessing an replacing parts you don't need . (fuel injector's ) Could be low fuel pressure , a bad MAP or MAF sensor. What are the fuel trims showing ? short term an long term fuel trims . Are the O2 sensor's switching normally ?

Yeah so bank 2 is the drivers side and 5678 are on that side you posted this in ford so it's either a 5.8 Windsor motor or a 5.4 and the camshaft sensor is on the timing cover under the valve cover about 2 inches or so go to rockauto.Com and look up your vehicle and the parts described here then you can see it before you buy it

What you need to do is check all the vacuum lines. Listen fro a hissing noise. it is leaking some where. Any time there is a MAF, and both 02 sensors pop a code, this is the first thing to check. And fords seem to leak the most.

Check engine light is on. don't have an owners manuel

There are many reasons for a check engine light to come on. If you are near a large auto parts store they will ususally hook it up to a computer and tell you what code is setting off the check engine light. The most common cause for a check engine light is a vacuum leak. This will usually show as an "engine lean" code. Meaning your engine is getting too much air in comparison to the normal amount of fuel. However, bad catalytic converter, faulty oxygen sensors, faulty exhaust gas recirculator, faulty positive crankcase ventilation valve could all be bad. It is too expensive to just replace everything, so getting the correct code from Autozone or Advance auto parts is important.

The onboard computer has detected a problem.

If still under warranty (emission related, up to 50K by government mandate), take to dealer. If not sure, take it to autozone or other auto parts store and have them hookup computer and printout the error code.

NOTE: If fuel cap is not on tight, it will set an error code. Can take several days to reset after correcting the gas cap.
