Can You Still Drive with Low Engine Pressure?

[OPatrick]

You cannot drive with low engine pressure. Engine mechanical system failure: For example, low cylinder pressure leads to reduced engine power, which is more prominent in cold conditions, or excessive carbon buildup on intake valves and intake pipes. Excessive carbon buildup on intake valves: This causes the injected gasoline to be absorbed by the carbon deposits instead of entering the combustion chamber. Engine management system failure: For example, incorrect signals for water temperature or intake air temperature, or wiring faults. Ignition system failure: For example, excessive carbon buildup on spark plugs or incorrect gaps, leakage in high-voltage wires or distributor caps, or damaged ignition coils. Fuel supply system failure: For example, fuel injectors not sealing properly or clogging due to excessive internal carbon deposits.
