Subject:quick question - running rough after 2 minutes
From:David Shepherdson

Quick follow up to the question that I posed a few days ago for the
record.

Major symptoms were that the van ran rough as soon as it warmed up
(temp needle to the bulb) and that turning the ignition off then on
again restored normal running for about 1 - 2 minutes until the symptoms
returned.  I got several good suggestions from list members, I
disconncted the O2 sensor and it ran fine so I replaced the O2 sensor
and it has been running fine for the last 250 miles (I think I am also
getting about 3mpg more).

87 Syncro

>>>>>>>
I just had 3 things go wrong with my 87 syncro.  First the low water
warning light came on a couple of times but I checked and water was not
low.  Then a hose blew out and because of the earlier false alarm I did
not stop until I saw drops of coolant on the rear window) lost about 2-3
quarts), the engine was definately hot but it seems OK now - time will
tell if the headgaskets were affected.  Now after temporarily repairing
the leak (with electric tape, coke can and 2 clamps) until I can buy a
new hose another problem has raised its head which I think is unrelated
(?).  The van runs great (this is when it is warm) for about a minute or
so and then starts to miss and sometimes will not pick up at all (dies
when the accelerator is depressed).  Turning the engine off then on
cures it completely for another couple of minutes.  Am I correct in
thinking that this is a classic O2 sensor failure (the computer being
reset to default values when the ignition is cycled off and then on)?
Many Thanks in advance,
David
