Volvo 850 Ignition System

Misfires, rough running under load, or an engine that hesitates in damp weather are common signs that the ignition needs attention on the 850's transverse five-cylinder DOHC engine. When troubleshooting, the distributor cap and rotor are typical checkpoints – traces of carbon deposits and crack lines can point to arcing, while a tired ignition coil often shows up as difficult hot starting or dropout at higher revs.
