Why do spark plugs have a smaller electrode gap?
Modified engines with higher compression or forced induction will typically require smaller electrode gap settings (to ensure ignitability in these denser air/fuel mixtures) as the voltage requirement at the electrode gap is increased due to higher combustion pressures. The electrode gap of a spark plug dictates the spark magnitude.
What happens if the spark plug part number is incorrect?
The part number you have entered is unknown or incorrect. The electrode gap of a spark plug dictates the spark magnitude. An incorrect electrode gap may affect engine performance as the spark magnitude may be insufficient to ensure complete combustion of the air-fuel mixture.

How does the zirconia work in an Isuzu troque?
The zirconia generates voltage from approximately 1V in richer conditions to 0V in leaner conditions. The heated oxygen sensor 1 signal is sent to the Engine Control Module (ECM). The ECM adjusts the injection pulse duration to achieve the ideal air-fuel ratio. The ideal air-fuel ratio occurs near the radical change from 1V to 0V.
How does the ho2s work in an Isuzu troque?
The HO2S generates a voltage between 0.1 and 0.9 V in response to oxygen in the exhaust gas. If the oxygen in the exhaust gas increases, the air-fuel ratio becomes Lean. If the oxygen in the exhaust gas decreases, the air-fuel ratio becomes Rich.
What is the p0138 code on an Isuzu troque?
The P0138 code is set when the Engine Control Module (ECM) detects that the rear O2 sensor signal voltage remains excessively high for an extended period of time. TECH NOTES: Replacing the Rear Heated Oxygen Sensor Bank 1 usually takes care of the problem.
