if you have the module off take it to a parts store(autozone/advanced auto,or whatever you have around your location) they should be able to test it for free. you may also want to check your pick up coil/coil and distributer.
Bad coils or perhaps a bad crankshaft position sensor.
If a defective ignition module, (or bad plugs/ wires) causes a misfire condition, one or more plugs won't fire. The uneven power pulses cause engine shaking.
At the front of the engine, behind a plastic cover, just above the exhaust manifold. There are 4 clips that hold the cover to the ignition module. Under the cover, there are 2 bolts that secure the ignition module to the engine. Disconnect the wiring plug on the end of the ignition module. Undo the bolts and use them to extract the module, then remove the plugs as normal.
The ignition module is located in the distributor under the rotor, it plugs in.
The ignition module is located in the distributor under the rotor, it plugs in.
In the front of the motor by the transmission dipstick. This is where your spark plugs from the engine go.
the ignition module is on the distributer(the thing all the spark plugs wires go to)
more apt to be the engine control module
Spark plugs are hidden under the plastic engine cover. You have to remove the ignition module as well which fits over the four spark plugs.
I have a '95 grand am quad 4, 2.3 liter engine. The 2.3 quad 4 engine has the spark plugs underneath the ignition module cover, which is the cover that has "Quad 4" written on it. You have to remove this cover to get to the spark plugs. To remove the cover, you have to first unplug the negative batter cable and then unplug the crankshaft sensor from the ignition module housing. The cranshaft sensor is the plug that is to the top right of the ignition module housing. After you have unplugged the sensor, you have to unscrew the four bolts that are on top of the ignition module cover. After you've done that, you can lift the cover directly up. This disconnects it from the spark plugs. When purchasing new spark plugs, make sure you get the right ones for the engine, adn you can ask the guys at the shop to set the correct gap for you.
Freeze plugs in a 96 Lumina are located at several places on the engine block. They are designed to expand and burst in a freeze instead of the engine being damaged.
The ignition control module is located under the electronic ignition control module cover. On a 1997 2.4L cavalier, it will have the words 2.4L twin cam stamped on it. It is on the top of the engine and is held in place with four bolts. This cover must be removed to get to the spark plugs.
