Spark plugs and wires
yes
It's called dual voice coils. There are two wires for bass and two wires for voice. It provides more quality. I, myself am looking to see which wires are negative and positive.
they are under the coil packs which are in the top of the valve cover, unplug the coil packs, take out six bolts, the wires should come out with the coil packs and you will have access to the plugs.
i think you disconnect one of the plug wires or you need to change one of them . It could be the oxygen sensor, valves, plug wires or a sticking fuel injector. You'll have to get a little more specific. If it ran well BEFORE changing the plugs and now it doesn't, perhaps 2 of the plug wires have been cross-connected.
In order to gain access to the spark plugs on a 2000 Alero, you must remove the cover on top of the engine that has the engine size. The cover is like a faux valve cover, once you pull it off, you can easily gain access to the spark plugs. You don't need to take off any cover if it's the 3.4 (3400). Look directly behind the radiator and you will see three wires going to the plugs. The other three are located behind the engine in the same location as the front. Just follow the wires and you'll do fine. On a 2000 Alero with a 2.4L, they are located under the cover from the top of the engine. They can be accessed by removing the four bolts on the top cover, then unplugging the wire connector located on the right side.
