hi does anyone know how to test the 2 switches at the back of the inletmanifold (yellow+brown)
if one of these wer faulty would they cause the car to hesitate under boost as my car is still doing it after i have checked :
plugs......regaped
tps.........checked with
multimeter ok
coil........new group a
leads....new 10mm
or has anyone got any ideas as to why my car is hesitating under boost
and only starts to do it when it starts to get warm (5minits of driving and it starts to hesitate under boost)
