What causes a car to run lean at idle?

If the root cause is an electrical problem within the idle air control valve itself, you will likely have to replace the IAC. A vacuum leak is a hole in a vehicle’s air intake system behind the mass air flow (MAF) sensor that allows unmetered air into the engine. This throws off the expected air fuel ratio and causes the vehicle to run lean.

Starting at cycle No. 5, we see that the exhaust generated vacuum starts the intake charge moving into the cylinder way before the piston even starts to go down the bore. As the crank rotates farther we get to cycle No. 1. This is what is normally considered the induction stroke that draws all the new charge in.

What causes an engine to stall at idle?

If the ISC valve is gummed up with fuel varnish or dirt, it may stick, preventing the engine from maintaining the proper idle speed when the throttle closes. A faulty idle speed control circuit may also allow the engine to stall when idling if it fails to compensate for idle loads placed on the engine by the charging system or A/C compressor.

Why is white smoke or steam coming from exhaust?

The causes of white exhaust smoke can vary; however, it is common to see white exhaust smoke when first starting a car, especially on cooler days. This is generally steam caused by condensation. As the engine warms up and the condensation dissipates the white exhaust smoke (steam) is no longer seen.

If the oil exits to the exhaust, the oil will be burned by the heat of the engine exhaust gas in the catalytic converter. So the smoke produced is white, if the oil is out to the intake then the oil will enter the combustion room and come burned during the power stroke that produces white smoke. 5. Wear of piston rings and cylinders block

Why does my truck Smoke in cold weather?

If condensation or cold weather isn’t the cause of your smoke, move on to Step 2. Coolant that is leaking into the combustion chamber will burn white and sweet.
