Problem Reported: EGR Orifice in Intake Manifold May Plug With Sludge and Cause Misfire
September 15, 2010, 10:09 PM

On higher mileage vehicles, one or more EGR orifice in the intake manifold may plug with sludge. This can cause the engine to misfire when first accelerating because too much exhaust gas is directed into the cylinders where the orifice is not plugged. Cleaning the clogged passages should correct this concern.
