Additionally, the intake manifold damper regulator occasionally malfunctions;
Usually, a dirty throttle or injectors are the cause of floating engine speeds.
The air flow meter and antifreeze temperature sensor have limited resources;
Frequent blockages in the crankcase ventilation cause thrust failures, among other issues.
