its either engine vibration,high rpm,black smoke!
Yes, it can cause drive-ability problems at all speeds under all conditions.
could be numerous things, like a faulty oxygen sensor/a.k.a O2 sensor, a faulty mass air flow sensor. it all depends on what year make and model of vehicle we are talking about
Carbon build up. Sticky or stuck EGR valve. Vacuum supply line damaged/leaking. Faulty EGR valve. Faulty EGR Position sensor/wiring.
A faulty o2 sensor / air mas meter will cause a car to run really bad. Shuddery and no power it could be your fault or Is your immobilizer cutting in? That could cause your fault Is your battery really low? Is the fuel out? Is there a light on the dash?
mass air flow sensor, O2 sensors, bad fuel pump
Because either that was not the cause of poor performance or you have multiple problems.
you may also check your mass air flow sensor one common cause is a faulty EGR valve. Check your computer diagnostics by using a code scanner.
What will a bad mass air flow sensor cause? Mass Air flow sensor regulates amount of air coming in to the amount of fuel being used. If this sensor is bad you would have either a overly rich or lean fuel condition. Check the fuel pump as mass air flow sensor has no moving parts and rarely goes out.
It does not have a MAF (mass air flow sensor)
throttle body sensor is a sensor that regulates gas flow. if your car is running sluggish sometimes this can confused with transmission problems when in all actuality its the sensor
Yes, a faulty mass air flow (MAF) sensor can cause a fast idle in a vehicle. If the MAF sensor provides incorrect readings, the engine control unit may deliver more fuel than necessary, leading to an elevated idle speed. Additionally, a dirty or malfunctioning MAF sensor can disrupt the air-fuel mixture, further contributing to irregular idle behavior. Regular maintenance and sensor checks can help prevent this issue.
A Subaru Forester may stall while accelerating due to several issues, including a malfunctioning fuel pump that fails to deliver adequate fuel to the engine, a clogged fuel filter restricting fuel flow, or issues with the ignition system such as faulty spark plugs or coils. Additionally, problems with the throttle position sensor or mass air flow sensor can disrupt the air-fuel mixture, leading to stalling. Checking for diagnostic trouble codes (DTCs) can help pinpoint the specific cause.
