Ok ... i got the throttle body cleaned.. new spark plugs.. still the same problem.... the car hesitates when i accelerate it hard ... especially on High rpms.. it feels like the engine is struggling . I took it to the electrician. After an hour of checking he finally decided to change a sensor that resides at the rear of the engine head on the top left side (near the cap for oil filling) . I dont know what that sensor does.. he said that the sensor is not working properly, so we connected the grip to a new sensor while the previous sensors was still at its place.. The car response improved...
then he removed the old sensor and put the new sensor in the place... connected it... The car started misfiring again !!!!! then he said that the sensor is not working when installed in its place.. then he left the new sensors inside the socket.. and connected the old sensor back again , now its hanging by the grip !!! WHAT KIND OF A SOLUTION IS THAT ???? the car is not misfiring ... but still engine is not accelerating properly !!
What i dont understand is how can a sensor not work when slotted at this proper position and then start working again when outside hanging !!!! ???????
Please advise me for an electrician in Rwp/Isb ... !!! cuz my fuel economy has got really low ..
before this problem .. my car was giving to 16+ ... now its around 9.... !!!!
