    code P0648

    I have just finished to rebuild the headcylinder on my 93 (misfiring + coolant leak). All joints have been replaced as well as the timing chain tensioner and injectors tested and cleaned. The car has restarted very well but a lot of vibration at idle. The returned code is P0648 (Throttle Body).
    I apparently will need the Tech2 to reset the throttle body, do you confim.

    I also notice on my car that it does not have the atmospheric pressure sensor on the right of the intake manifold (close to the steering pump) ?

    Any comments ?

    Thanks for your help

If you want to know how long we can driving with a misfiring cylinder, visit here for more info
    I think you try to clean throttle body first. Check the park plug. if worn out spark plug can prevent the fuel-air mixture to not get properly ignited in the cylinders, thus leading to misfiring. This can result in the engine to vibrate as the cylinders can misfire during idling. Hope it can helps.
