4KQ OXS & rev limiter ?

[Glen_Powell@ne.3com.com]

I need to get like 300-500 more RPM before the rev-limiter stops the fun.
Any easy ways to do this? Is this controlled by the fool-pump relay? Could
the relay be modified to increase the rev limit?

Another question: I replaced the 3-wire heated oxygen sensor in my 84 4KQ
RR car and also replaced the faulty HalMeter AF30 mixture meter. The meter
works OK now but it appears that the system never goes closed-loop. Is this
because the sensor does not get hot enough without the integral heater?
Does something sense the open-circuit for the heater and disable
closed-loop mode? I would have thought that the heater was just for faster
warm-up for emissions purposes and that it would eventually get hot enough,
guess not?
