Just for giggles check your O2 sensor as well.
I had both white wires disconnect on mine and aside from illuminating
a MIL it made the truck run like shit at constant throttle settings.
it would sputter, sometimes stall at idle, either backfire or light
off raw fuel in the catalytic - I'm not sure which. I think a sensor
on it's last legs reporting bad values could potentially do the same
thing.
diagnostic method: unplug it and see if the situation changes.
thoughts?
