Can a restricted air filter cause engine problems?
It keeps the undesirables (dirt and debris) out while letting power-producing air in. A restricted air filter can cause many problems, including an illuminated check engine light. Engine airflow performance. Besides keeping contaminants out, an air filter must allow unrestricted airflow into the engine.
Can a blocked air filter cause a check engine light?
A blocked air filter can prevent the turbocharger from building sufficient boost pressure. Since turbocharger performance is monitored by the ECM, lack of boost pressure can cause the ECM to turn on the CEL. It should be noted that the air filter must be extremely restricted to turn the CEL on in a modern, naturally aspirated vehicle.
What happens when a car air filter becomes clogged?
Most modern vehicles have a mass air flow sensor (MAF) mounted downstream from the air filter. If the air filter becomes clogged, the ECM will adjust the air/fuel mixture, using input from the MAF.
Why does my engine go into limp mode?
The reason for this is that limp mode could be caused by a lot of different engine components in your engine bay. Therefore, the solution for this is to read the trouble code memory with an OBD2 scanner to find the problem before you are replacing any engine parts! Here is a list of different possible causes of limp-mode.

Can a bad throttle position sensor cause idle surging?
Idle surging can be caused due to other issues in the car, but if it happens in conjunction with other throttle position sensor symptoms, the culprit is often the TPS. At idle, the ECM will not get the correct information and the throttle will variate randomly causing idle surges. 3) Check Engine Light
What happens if your air filter is clogged?
Most modern vehicles have a mass air flow sensor (MAF) mounted downstream from the air filter. If the air filter becomes clogged, the ECM will adjust the air/fuel mixture, using input from the MAF. This smooths out engine performance and often prevents the CEL from being turned on.
