Modern gasoline powered internal combustion engines operate by using a spark plug to detonate a fuel/air mixture in the cylinders. However, the 12 volt system that most vehicles use doesnt provide enough energy to create a sufficient charge to power the spark plug. Theore, an ignition coil is required to transform the 12 volt charge into a charge of up to 30,000 volts or more. If the vehicle begins to lose power or run badly, one possible cause is a faulty coil.
Instructions
1 Use a 4mm allen wrench to remove the four bolts securing the engine cover to the engine.
2 Use a socket wrench and 8mm socket to remove the two bolts that secure the coil pack to the engine.
3 Pull the coil off the spark plug by pulling it straight off, using a twisting motion.
4 Disconnect the wire from the coil by pushing in on the green tab on the coil, and then pulling the wire off the coil pack.

A malfunctioning car alarm on your 1998 Nissan Altima can keep you and your neighbors up at night. If you are having problems with the alarm, you can disconnect the alarm system from the power supply to keep it from going off. Disconnecting the alarm from the power supply is not very hard. The power supply is your car battery and the alarm is wired into the negative terminal.
Instructions
1 Pop the hood to your Nissan Altima.
2 Locate the negative terminal labeled with a "-" mark.
3 Use a pair of channel locks or a socket wrench to loosen the negative terminal.
4 Pull the negative terminal off of the battery to disable the alarm.

You can manually read the trouble codes set by the diagnostics computer in your 1994 Nissan Altima right from your garage, saving both time and money. The 1994 Nissan Altima has an "Onboard Diagnostics I" computer (OBD I) that retrieves and stores all trouble codes sent to it from sensors positioned throughout the vehicle. When these sensors detect any malfunction in the Altimas powertrain, they send trouble codes to the computer. The computer, in turn, illuminates the warning and service lights on the instrument cluster. You can retrieve these codes using an OBD I code scanner. You can purchase an OBD I scanner at any auto parts store.
Instructions
1 Locate the data link connector (DLC) port on the driver-side dashboard under the steering column. Its the same size and shape as the connector on the OBD I code scanner. Carefully plug the code scanner into this port.
2 Put the key into the Altimas ignition and turn it to the "on" position, but dont start the engine. Wait for the code scanner to power on.
3 Select the command "Read Codes" or something similar. Wait while the code scanner retrieves the codes. Write the codes it displays down on a piece of paper.
4 Look up the codes in the scanners manual to get an exact diagnosis. Unplug the scanner and have the vehicle repaired or serviced based on the information obtained from the codes.
