## Questions & Answers

**Q: What are the symptoms of a bad ignition coil?**
A: A failing ignition coil can cause several symptoms, including the “Check Engine Light” appears, engine misfires, difficulty starting the vehicle, reduced fuel economy and loss of power during acceleration.

**Q: How often should spark plugs be replaced?**
A: Spark plug replacement intervals depend on the type of spark plug and the vehicle’s engine. Refer to your vehicle’s Owner’s Manual for more information.

**Q: How can I tell if my distributor cap and rotor need replacing?**
A: Distributor caps and rotors typically need replacement when you notice engine misfires, difficult vehicle startup, reduced engine performance, corrosion or carbon tracking on the cap, or cracks or wear on the rotor.

**Q: What is the difference between glow plugs and spark plugs?**
A: Glow plugs are used in diesel engines to preheat the combustion chamber for a cold start. Spark plugs are used in gasoline engines to ignite the air and fuel mixture.

**Q: Does the "Service Engine Soon" light tell me when my vehicle needs a tune-up?**
A: No. The "Service Engine Soon" light comes on when the vehicle’s computer detects a minor malfunction, an engine emissions issue or that routine maintenance is needed. For more information, refer to your vehicle owner's manual.

### ⭐⭐⭐⭐⭐ AC Delco
*by T***T on July 28, 2013*

Replaced the cap and rotor as preventative maintenance. Old ones were very worn with some deposits but had not yet developed a misfire. Parts fit, wires snapped in confidently. Comes with two new Torx Screws; the rotor also does so you have extras if you drop one into the depths of the engine compartment. Not the easiest to install on a Suburban with 29" tires though. The torx bolts are what makes it a PITA. A Phillips head would have been fine, and allowed much easier installation. The screws are easy to drop as are the tools you are using due to it being tucked so far back against the firewall, and set so low. You cant really see what you are doing in there. However, this has nothing to do with the part's quality - just a heads up. Other Gm vehicles have been much easier, with screw heads that either a Phillips OR a standard can fit with locking springs; all you do is press down and turn 90 degrees. I certainly didnt expect two different sizes of Torx heads in there.
