Ignition Coil
WARNING: This page is about a different car, the 1993 Volkswagen Passat. However, it is still accessible from the selected car via links, so may be relevant.
Connect Digital Volt-Ohmmeter (DVOM) between coil terminals. Primary coil resistance should be .60-.80 ohm. Connect DVOM between coil tower and coil positive terminal. Secondary coil resistance should be 6500-8500 ohms. If resistance values are incorrect, replace ignition coil.
