Well the =
intermittent missfire
you speak of because of the Internal head leak is not similar to =
the
intermitant violent (emphasized) jerking of =
the
more mysterious problem related O2 sensors and AFMs that are =
fixed with
"harnesses". I experienced this jerking once and =
only
once ever and never again, acctually twice for a matter of =
seconds
on one day, who knows?
There
is a great difference!
I do however have the internal head leak which I =
believe
has been worsening for the past few years. A few mechanics =
tried
to find the problem to no avail. I only realised the =
acctual
problem this summer on the way to maine to see Phish (there were =
plenty
of warning that this problem was happening, but I was young and =
a
newbie.) when my coolant light =
started
blinking, the heater started blowing cold air =
intermitantly for a
while before the blinking.
So
much exaust gas accumulated in the cooling system that the =
sensor in the
resevoir was responding to the fact that all that surrounded it =
was
air. I pulled over and bled the system of air and topped =
off the
coolant (I was well prepared), and off we were again. This =
happened once again on the way home.
To
make this increasingly longer story short.
It sounds to me like you =
need to do
the heads. Feel lucky that you discovered the
list.I did not find it 'till =
last year
and still took forever for me to find the real
problem.
Who knows what other damage I have done by driving with =
this
persitant problem! (feel
free to comment on the possibilities, anyone? she seems to =
run
fine other than the leak.)
One
last comment: Early on when I noticed slight hesitation on =
take
off, hills, ect. I unplugged the oxygen sensor and this =
remedeied
the hesitation (not too smart). I later plugged it back in =
and it
still ran fine but by this time the sensor was probly
dead.
