how do u test yellow+brown switches on erst
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)

a problem everyone with an ERST seems to experience at some point, i personally think the problem lies somewhere in the realms of BOSCH KE JETRONIC IS A BIG PILE OF SOAPY WANK
the brown one wont have anything to do with it, only comes into play when cranking (thats if you have one of the few that will actually start with the cold start valve connected!!!!), and the yellow one, possibly, but VERY VERY unlikely.
Just so a resistance test, the resistance changes with temperature, very rare thing for these to go wrong.
you could look into your air temp sensor, although again unlikely?
if you can mate get fiesta/cosworth management and be done with it!!
