What are the causes of engine power loss?

[McIsaac]

The causes of engine power loss are as follows: 1. Cause one: Issues in the fuel and electrical circuits, such as obstructed fuel lines, restricted air intake leading to overly rich air-fuel mixture, delayed ignition timing or excessive contact gap, exhaust pipe leakage, leaking or detached high-voltage wires, distributor socket leakage or cross-firing, uneven wear of distributor cam or excessive carbon buildup and damage in spark plugs causing leakage. 2. Cause two: Insufficient cylinder compression, unsealed or burnt cylinder gasket, burnt or unsealed valve seats or their detachment, weak or malfunctioning valve springs, seized or misaligned piston rings, excessive clearance between piston and cylinder. 3. Cause three: Overheating of the engine, malfunctioning water pump or thermostat, belt slippage, excessive scale buildup in the cooling system. 4. Cause four: Some cylinders not functioning, incorrect valve timing, chassis issues, clutch slippage, brake dragging, low tire pressure.
