My 96 century with a 3.1 v-6 gave me fits for years shooting a 171 code(running too lean) I wound up changing the fuel filter and the problem went away. If it's been a while since the filter was changed, try it.
Its most likely a clogged or malfunctioning fuel injector. Unplug the injector wire harness and check contacts for corrosion. If there is corrosion clean it with some electrical contact cleaner spray, apply some dielectric grease before reattaching it. If that doesn't work you can buy some fuel injector cleaner, the aerosol type that attaches to the fuel rail, not the gas additive type.
Remove the cover on top of the engine. It has fouth 10mm bolts that hold it on. This car has individual ignition coils for each cylinder. Remove the wiring harness connectors from each one, then remove the ignition coils. Check each coils resistance with an ohm meter, they should all have about the same resistance. If one is really low, high, or has no continuity, it will need to be replaced. You will notice that the coils have what is called a "plug boot" attached to each of them. First inspect them, and make sure there are no burnt places on them. If they have oil on the, you will need to replace the valve cover gasket. Next remove the plugs, and inspect/replace them. Assembly is reverse of removal. This should take care of it.
If you have a 1997 Skylark w/ a four cylinder engine, then you have the same one I do, a 2.4L dual overhead cam. It is not a quad 4, different beast altogether. I believe your problem might be the plug boots, did you replace them? It's a relatively cheap solution, about $17 at AutoZone if I remember right.
I have had the key cylinder changed twice on my 96 Buick Skylark Grand Sport and still having the same trouble. The car will start, it runs for about 3 seconds and shuts off with the theft system light on. I have reset the computer time and again and the car WILL run great for a day or two and then it gets back into the same routine. Is there a way to bypass the theft system? If so... PLEASE help me out before I take a hammer to it.
