Routine occurrences of prolonged idle time may result in excess wear to the engine camshaft lobes and valve tappet surfaces due to reduced lubrication. Over time, the engine may progressively run rough due to cylinder misfire. Additionally, customers may hear engine tapping noises and the Check Engine Light (CEL) may illuminate.
