Would turning off the engine and then back on also cause the ECU to default
other components temporarily, such as the mass air flow sensor and therefore
not pinpoint the O2 sensor?


Howdy,
 I  just picked up an 87 2wd Westfalia- the plugs, wires, cap, rotor and all
fluids  are new. I also replaced the ground on the O2 sensor. I have put two
tanks of  gas through it, one with fuel injector additive. Anyhow, the van
runs well most  of the time but intermittently starts missing on what I
think are two cylinders.  This happens when I am holding the gas steady and
stops happening if I floor the  gas pedal rather abruptly. A few seconds
after I take the pedal off the floor,  it starts missing again.
 Does  anyone else recognize these symptoms and have any  suggestions?
 Thanks
 Shawn
 Portland  Oregon

Sounds like an O2 sensor issue. To confirm, when it happens, hold throttle
steady and turn ignition off and back on. If it works ok for a short while,
then definitely O2 sensor or wiring for it.
