I AM NOT A MECHANIC,
but I have read on this list that your type of problem may be caused by
moisture shorting out your brand new O2 sensor.
Others may have more to say on this subject - if I am wrong, I hope others
correct me.
Keep your chin up - you'll get this sorted out in no time - the list knows
all.
Cheers!
