Besides, your engine is probably running better (maybe) because you placing your hand there doesn't entirely kill the engine but simply makes the air - fuel ratio rich (this makes the engine smile).

Air / Fuel Mixture: Lean air / fuel ratios raise cylinder - head temperatures, requiring a colder plug.

This isn't something to be surprised about since the ECU can estimate air - fuel ratio using the MAF signal and injector pulsewidth.

It's quite simple if we can treat each fuel and its stoichiometric air fuel ratio separately, but when it turns to flex fuel cars I can't get a conclusion.

Unlike gasoline engines, diesel engines vary fuel flow to control power, rather than throttling air intake and maintaining a constant fuel ratio as gasoline engines do.

When you accelerate, the engine RPM increases, and as you let off the gas, the RPM slowly returns to the normal idling speed with the help of the idle air control valve making the transition from a higher RPM back down to idle speed while adjusting the air / fuel ratio constantly to allow this to happen smoothly.

This is controlled by the car's ECM which uses this information to make adjustments to the air / fuel ratio depending on various inputs such as outside air temperature, intake air temperature, load and various other things.

ETC provides some benefit in areas such as air - fuel ratio control, exhaust emissions and fuel consumption reduction, and also works in concert with other technologies such as gasoline direct injection.

The PCM uses the air flow signal to calculate the proper amount of fuel injected into the cylinders in order to keep the air / fuel ratio at the optimal level.

Check Engine light with the codes P0131 / P2251: The Technical Service Bulletin 01-015/10 recommends checking the front air / fuel ratio harness where it rubs against the bracket.

The exhaust manifold is cast into the cylinder head, which lowers exhaust gas temperatures and allows the engine to run with the optimum air - to - fuel ratio across a wider rev band.

It makes sense, since an air fuel ratio sensor deteriorates over time anyway.

Other performance additions include an AEM cold - air intake, BBK shorty headers and a custom straight - piped exhaust with custom tips, a custom tune, AEM air / fuel ratio gauge, and an SR Performance strut - tower bar.

Rich air / fuel ratios require a hotter plug to prevent fouling.

The Skyactiv - G 2.5 T has allegedly overcome these issues thanks to the Dynamic Pressure Turbo, the world's first turbocharging system that can vary the degree of exhaust pulsation depending on engine speed, and a cooled exhaust gas recirculation (EGR) system that allows the engine to maintain the ideal air - fuel ratio over a wider output range.

the 1st one closest to the engine does pretty much all the work for air / fuel ratio in most non-new generation cars.

However, could it be that the AFM data will be used to provide the correct air fuel ratio, as long as the AFM data is not obviously incorrect?

The Saab team members, led by Olofsson and Lars Bergsten, 62, knew that if they could just keep the same air - to - fuel ratio but fill, say, only half a cylinder, they could cut fuel consumption by 10 percent.

Most vehicles which are OBD - II compliant (newer vehicles are a little different) use just the O2 sensors located before the cat to adjust the air / fuel ratios.

You want just enough idle jet for a good idle quality, then choose your main jet for the rest of the fuel ratio.

Your car idles high in the cold because of poor air / fuel ratio.

I would go with the upstream 02 sensor - that is one that controls the air / fuel ratio.

Suppose the engine is at a steady 3000rpm, then the air - fuel ratio will remain at some constant value, and hence the upstream O2 sensor ought to give a constant reading on an oscilloscope, rather than some kind of wave.

These are air - fuel ratio sensors not standard oxygen sensors.

Consider also vacuum leaks as the potential cause, as a vacuum leak can affect the air / fuel ratio.
