The 1.9 in my 84 has exhibited the idle hunt occasionally of late. I solved
the loss of power and hot start problem with a new O2 sensor. I am going to
check the engine grounds again as your email below recommends. This may
solve another problem probably related. The idle cannot be adjusted to run
lower than 1500. Thanks for the 1.9 specific advice.
