Inspection woes

[Tunerfreak]

@HotRodKid

if its internal, maybe just take the spring out (as long as the diaphram has enough play in it)

the pieces FIP speaks of is the old trick with spark plug antifoulers, get 2 for every O2 sensor, drill one out all the way, leave the other one stock, then screw them together in this order:

o2 - big hole antifouler - unmodified antifouler - exhaust pipe

yes its externally gated and the spring is already out

where do you get these spark plug antifoulers any car store, is that what they are called?
