WARNING: CA Prop 65 - Cancer and Reproductive Harm Review: Perfect Fit: Fixed My Misfire and Smoothed My Idle - I recently purchased this ACDelco ignition coil to address a persistent misfire issue on my GM vehicle. Opting for the Original Equipment (OE) part is almost always the safest and most reliable route for these specific engines. The packaging was secure, and the part arrived in perfect condition without any signs of damage during shipping. Installation was straightforward, taking me less than fifteen minutes with just a few basic hand tools. It fit perfectly into the engine bay, matching the factory dimensions exactly as you would expect from a genuine GM component. After swapping it out, I immediately noticed that the engine idle smoothed out significantly. The hesitation during acceleration that I had been experiencing completely disappeared after a quick test drive. It feels great to have the vehicle running reliably again without having to pay expensive dealership labor rates for a simple fix. The performance is indistinguishable from the original coil, confirming the high quality of this replacement part. I highly recommend this item to any DIYer looking to resolve ignition issues on their GM vehicle with a trusted brand. One last plus was the price for these!

Refer to your vehicle Owner’s Manual for guidance on when you should change your vehicle’s spark plugs. **Q: Should I change all of my vehicle’s spark plugs at the same time?** A: Yes, when it is time for a scheduled spark plug replacement, all spark plugs should be changed. If a single spark plug is fouled or damaged outside of scheduled maintenance, finding the source of the damage and changing it is recommended. **Q: Can I just clean my spark plugs instead of replacing them?** A: No, ACDelco does not recommend cleaning old spark plugs. Cleaning spark plugs does not repair broken components, chipped insulator tips, and worn electrodes and wires. **Q: What is pre-ignition and can it damage my engine?** A: Yes, pre-ignition can cause serious damage to an engine. Pre-ignition, often accompanied by engine knocking sounds, air and fuel ignite in the engine before the spark plug fires. The condition commonly occurs when old spark plugs are worn or dirty. **Q: Does a diesel engine require a different type of plug than a gas engine?** A: Yes, diesel engines require glow plugs instead of spark plugs. To learn what type of glow plugs or spark plugs your vehicle requires, refer to your vehicle Owner’s Manual for guidance. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect Fit: Fixed My Misfire and Smoothed My Idle *by E***N on April 21, 2026* I recently purchased this ACDelco ignition coil to address a persistent misfire issue on my GM vehicle.
