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
