What causes the surge in a car engine?
Proper engine performance is dependent on a very precise balance of air/fuel mixture, spark timing and exhaust management; any deviation from any of these parameters will cause malfunction, which is often expressed as “surge” (rapid acceleration/deceleration cycles).
What causes a PowerStroke to overheat or fail?
Excessive heat from the engine and vibration can cause the FICM to overheat or fail. This occurs because the FICM is located on the side valve cover of the Powerstroke engine. Cold starts impact the FICM negatively by causing excess voltage to be drawn.
Why does my 6.0L Powerstroke stick open?
The EGR Valve on the 6.0L Powerstroke regulates the amount of exhaust gases that are reintroduced to the engine.

Often times this occurs due to excessive idling or poor fuel quality.
Why does my Rogue shake at low rpm?
Vehicle Speed: A Misfire can be felt at any speed, but is most noticeable at low RPM. A misfiring engine is one of the most common reasons your Rogue will shake when accelerating.
