Signs of a Failing Distributor Cap on a Dodge Spirit
A bad distributor cap can cause a range of engine problems. Because the cap is a simple part, the signs of failure are usually straightforward. Look for issues like engine misfires, trouble starting, or a rough idle. You might feel the car shaking or jerking, especially when you're accelerating.
Check Engine Light
A failing distributor cap can cause the Check Engine Light to come on. If the computer detects a misfire, it will store a trouble code. Common codes related to misfires include P0300 (random misfire) or P0301-P0306 (specific cylinder misfire).
Visually inspecting the cap is the best way to confirm it's bad. Remove the cap and look inside for cracks, moisture, or white or greenish corrosion on the metal terminals. Also, check the center button; it should be spring-loaded and not worn down or stuck.
Choosing the Right Aftermarket Distributor Cap
For a vehicle like the 1989-1995 Dodge Spirit, aftermarket parts are the most common and affordable option. Original Equipment (OEM) parts from Mopar may be difficult to find new. Aftermarket quality is generally good and meets the needs of this vehicle's simple ignition system. When choosing a brand, focus on the materials.
- Brass vs. Aluminum Terminals: Look for caps with brass terminals. Brass is a better conductor and more resistant to corrosion than the cheaper aluminum terminals found in some budget parts.
- Material Quality: Better quality caps are made from high-dielectric materials that resist heat and prevent electricity from leaking.
Here's a look at the brands available:
- Standard Ignition (Blue Streak): Often considered a premium aftermarket brand, Standard Motor Products (SMP) parts are well-regarded. Their Blue Streak line is marketed as a higher-quality option.
- Facet: A brand offering parts that meet OE specifications for fit and function.
- Walker Products: Walker is known for engine management and fuel system components, and they offer distributor caps designed to OE quality standards.
For a daily driver, any of these brands with brass contacts will provide reliable performance. It is highly recommended to replace the distributor rotor at the same time as the cap.

Frequently Asked Questions (FAQ)
Can I replace the distributor cap myself?
Yes, this is a very DIY-friendly job for most people. You will need basic hand tools like a screwdriver or a small socket set. The most important part of the job is to transfer the spark plug wires from the old cap to the new cap one at a time to avoid mixing up the firing order. It's also a good idea to mark the position of the distributor before you start.
Should I replace the rotor with the cap?
Yes, you should always replace the distributor rotor when you replace the cap. The rotor is a wear item just like the cap and is located directly underneath it. Replacing both at the same time ensures the entire secondary ignition circuit is refreshed and only costs a few extra dollars.
Were there any recalls for the Dodge Spirit distributor cap?
No. Searches of the National Highway Traffic Safety Administration (NHTSA) database did not find any recalls specifically related to the distributor cap or ignition system for the 1989-1995 Dodge Spirit.
What is the difference between a cheap and expensive aftermarket cap?
The main differences are the materials used for the terminals and the cap body. More expensive caps typically use brass terminals, which offer better conductivity and corrosion resistance than aluminum. They may also use a higher-grade plastic that is more resistant to heat and high voltage, preventing cracks and carbon tracking.
Technical Specifications
Varies by engine (2.5L I4 or 3.0L V6). Ensure the cap matches your vehicle's specific engine. The cap is held on by clips or screws.
