Idle Speculation

If your vehicle idles roughly, hesitates, and/or stalls, there may be a problem with the exhaust gas recirculation (EGR) valve. This component recirculates a small amount of exhaust gas back into your combustion chamber, where it is reused in efforts to increase engine efficiency and reduce pollution. If a mechanical EGT is stuck open, it will cause a vacuum leak that will lead to inefficient combustion. This is due to the fact that the engine’s combustion chambers will be flooded with exhaust gases and less-needed atmospheric oxygen. If the EGR valve is stuck closed, emissions of nitrogen oxides will rise and the vehicle may begin to “Knock”. Either way, cleaning or replacement of the valve may solve the problem.

Hint: Because an electronic EGR valve uses electronics to regulate function and is more complex than a mechanical EGR valve, it may simply require replacement in the event of failure.
