The typical cause of problems for ignition coils would be corrosion from air flow or exposure to any chemicals, lubricants, solvents, or cleaners in common use around the motor. The connecting points will get corroded causing a lower grade spark and possibly intermittent spark. Coils will occasionally fail altogether internally becoming useless, but this is rare. In older cars with distributors and ignition points, coils sometimes overheat from current strength and would melt the wires connected to it.
How do I know if I am having coil problems?
If you have a complete coil failure, it would be easy to tell as your car won't start. If you have the more common corrosion problem, then it all comes down to a weaker and intermittent spark as the transmission of your electrical current will be disrupted. Symptoms of this problem include hesitation while starting the car, weak throttle response during acceleration, rough idle, misfiring, backfiring, and dim or weak accessories like the headlights and radio.

The ignition coil is built inside the distributor on a 2000 Chrysler Sebring 2.5L.
To change the ignition coil in a 2002 Volvo S60, first, disconnect the negative battery terminal to ensure safety. Then, locate the ignition coil on the engine; it is typically situated on top of the spark plugs. Remove the electrical connector and the mounting bolts for the coil, then pull it out. Install the new ignition coil by reversing the process, reconnecting everything securely before reattaching the battery terminal.
The car has two coils they sit on the sparkplugs for cylinders 1&2. There are wires which go to cylinders 3&$ from the coils.
This model probably has the Regina engine. The ignition coil should be mounted on the drivers side fender well close to the firewall.
To change the ignition coil on a Volvo 740, first, ensure the engine is off and disconnect the negative battery cable. Remove the ignition coil's electrical connector and unscrew the mounting bolts securing the coil to the engine. Replace the old coil with a new one, reattach the mounting bolts, and reconnect the electrical connector. Finally, reconnect the battery and start the engine to ensure proper operation.
it is the ignition coil is the problem replace it p0135 for Volvo not sure about p1081
On a 2001 Volvo S40, ignition coil B is located on the engine's cylinder head, specifically for the second cylinder from the timing belt side. The ignition coils are arranged in a line, with each coil corresponding to a specific cylinder. To access it, you may need to remove the engine cover and possibly other components obstructing the ignition coil. Always refer to a repair manual for detailed guidance specific to your vehicle.
On my 90 740gl it is right next to the ignition coil. It depends on the ignition system used. On a Regina ignition, I think everything is built in the coil (The big square one) The regular round coil is for BOSCH ignition and a separate module is use. NOT SURE, would appreciate confirmation.
Yes, a bad coil will prevent the ignition from firing and the engine will not start.
The coil on a 2.5L is built inside the distributor.
