If the Mass Air Flow sensor has failed will it behave the same when it is disconnected or should the car run diferent with the sensor unplugged.
What about the Oxygen sensors can they effect performance?.
Right now the Car Runs with very poor excelleration and response.
I have changed all the ignition coils, have no air leaks pipes etc, Changed Fuel filter, Air filter and CAM Sensor and still it runs terrible it idles good but as soon as you put the power on it dies and coughs and splutters
Desperate.
