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.
You may have a faulty coil. Check mass air flow sensor
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
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.
Because either that was not the cause of poor performance or you have multiple problems.
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.
Rough Start, Low power will feel like car is starving for fuel. Unplug the mass air flow sensor and start car it should go to default mode and if it runs fine you have a bad mass air flow sensor.
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
