    Default corolla 2007 xli rpm dropping problem in slow

    my toyota corolla xli 2007 is having rpm dropping problem. Its a manual car. When i pick up from first gear and give it a speed through speed padel it instantly drops the rpm then return back to normal level. Its mostly happening with air conditioner. We tried every possible thing for this like coils checking, changing of plugs, injectors cleaning, throttle body cleaning etc. We also have gone through with car computer scanner. Its all clear and not giving any sort of sensor or other ecm related fault. I am confused about the next step to sort out this problem. Please help me out

    Default Have you tried changing Ignition Coils ?

    If you have just checked the COILS there is no way you can check the coils the only way to diagnose is to change the Coils it is not waste thign to do , it will return your investment thru mileage, i am pretty sure , or check MAF Sensor

    Let know here whats the result i can help finding right coils for your car infact we have in stock

    There is a sensor on throttle body of the efi engine. That sensor is called MAF sensor majorly responsible for idling and rpm settings.
