Is it Time for New Spark Plug Wires?
Worn-out spark plug wires are a common cause of engine problems in the Chrysler Cirrus. When the wires can no longer deliver a strong, consistent spark, you'll likely notice one or more of these symptoms. Ignoring them can lead to poor fuel economy, failed emissions tests, and potential damage to other expensive components like the catalytic converter.
Symptoms of Failing Wires
🎬 Watch this video to see common symptoms of bad wires.- Rough Idle: Your engine may shake or vibrate noticeably when you're stopped at a light.
- Engine Misfires: You might feel a hesitation, stumble, or jerking from the engine, especially when you accelerate. This can also cause the Check Engine Light to flash.
- Reduced Power: The car may feel sluggish and slow to accelerate.
- Worse Fuel Economy: When cylinders don't fire properly, the engine burns fuel less efficiently, and you'll find yourself at the gas pump more often.
- Difficulty Starting: A weak spark can make it harder for the engine to turn over, particularly in cold or damp weather.
Pro Tip: For the best results and to save on future labor, it's highly recommended to replace your spark plugs at the same time you replace the wires. New plugs and wires ensure the entire secondary ignition system is refreshed.

Frequently Asked Questions
How do I make sure the new wires go to the right cylinders?
The best and safest method is to replace the wires one at a time. Remove one old wire, match its length to a new wire from the set, apply a small amount of dielectric grease to the inside of the new boots, and install the new wire in the exact same path. This prevents mixing up the engine's firing order, which would cause it to run poorly or not at all.
Are there any recalls for Chrysler Cirrus spark plug wires?
No. A search of the National Highway Traffic Safety Administration (NHTSA) database shows no recalls specifically related to spark plug wires for the 1995-2006 Chrysler Cirrus. There were other recalls for this vehicle, but none address the ignition wires.
Can I replace just one bad wire?
While you can, it's not recommended. Spark plug wires degrade at a similar rate. If one has failed due to age and heat, the others are likely not far behind. Replacing them as a complete set ensures consistent performance and prevents you from having to do the same job again in a few months.
What are TSBs and are there any for my Cirrus?
A Technical Service Bulletin (TSB) is a notice from the manufacturer to technicians about common problems and recommended repairs. One relevant Chrysler TSB (08-008-04) for the 2.4L engine notes that when changing to a newer style of spark plug for the first time, the ignition cables should also be replaced to prevent issues. This highlights the importance of replacing plugs and wires together.
