| SYMPTOMS | Common signs of a worn or sticking lifter include persistent ticking/‘sewing machine’ noise, rough idle, reduced power, and misfire DTCs such as P0300 (random/multiple misfire) or P0301–P0308 for specific cylinders. |
| TROUBLESHOOTING | Before condemning a lifter, confirm correct oil level/viscosity and oil pressure, listen with a stethoscope to isolate the noisy cylinder, and check for misfire counters. Random misfire P0300 can also be caused by ignition, fuel, or vacuum issues; rule those out per diagnostic references. |
