code 232 came back again after 100 miles or so,My Clymer manual says check intake manifold or O2 not working either rich or lean.I resealed the intake and injectors with no improvement and did many of the faq section items on the brickboard,with 170k on the original injectors maybee it's time for them to be cleaned or replaced.The amm is new and reads the same 2.50 volts at idle as the old one(faq says 2.30 volts or try a known good amm) but I have yet to replace the O2 sensor,it is does cycle from .2-.70 volts at idle but maybee not fast enough,the O2 does have 90k miles on it.The
2-3-2 never makes the check engine light come on either,I guess it may be not serious enough to throw the check engine light but will store it in the memory of the fuel ecm.Fuel pressure reg unit is recently replaced on last tune-up with cap rotor and wires,fuel filter as well.I have read many 2-3-2 posts in the archives and for the b234 it is most disturbing what I have read,I even read a post about having to replace amm,ecm,and O2 and I hope I'm not heading in the same direction.Any imput would be greatly appreciated.
