Hi,
Replace the Temp2 sensor, if not done so already. It is cheap to replace,
and more often than not, it is the culprit with temperature related loss of
power, stalling, and difficulty to start when hot. This may not be it, but
always start with the cheapest parts first, one at a time, when fixing by
trial and error.
Also, when I had this problem 10 years ago, it was intermittent. Tested OK
in the shop, but failed unexpectedly. Finally a one car garage mechanic
made the connection: Problem is temperature related, Temp2 sensor, BINGO.
Put in a new Temp2 sensor, and like magic the van ran like new. It had no
choice, because the dealers mechanics, with all their certificates on the
wall, could not put two and two together. They replaced almost every part
there was to replace, except the Temp2 sensor.
Thank God for this List!

Hi list -
I'm having problems that seem identical to what Kim is describing and would
love to hear about possible solutions. I had a similar, but slightly
different problem about a year ago when the car would lose power but never
stall. While still trying to figure this out, the fuel pressure regulator
died on me. At my mechanic's suggestion, I replaced the AFM at the same
time I replaced the fuel pressure regulator. This solved my problems...
for a while.
Recently the van has started to exhibit loss of power and random stalling
in the way Kim described in her email (below). I replaced the fuel pump
and filter in hopes that it was simply a fuel feed problem. It made things
a bit better (I think my previous pump was having problems) but this didn't
solve the problem.
I'm baffled. The mechanic I usually take the van to is baffled. The only
thing he can think of is that maybe the ECU is shot. I'm sure that a shot
ECU could cause these problems... but I'm not yet certain that it's the
only thing that could cause them. Any suggestions from wise list members
will be appreciated!
thanks
Russell
by the way, my van only has the little plastic fuel filter between the tank
and the pump. Is it supposed to have the bigger round filter downstream of
the pump too???

Hi List,
i am having troubles again...here are the symptoms.
Loss of power, or like the van is getting no fuel sometimes. It has
happened
cruising the freeway at 75 mph, and sitting at a stoplight waiting to turn.
It has happened about 5 times since on my drive back to MN from IL on
sunday.
The first time the van did this, it was sorta hot outside, cruising the
freeway at 75mph, finally had to pull off the road, and i found the
alternator to be loose in the mounting bracket, and I unplugged and
replugged the TEMP II connection thinking that was the problem. Then it
started up again and drove normally for another hour or so, then it started
loosing power again. after wiggling wires around, it started up and we
were
back on the road again with no problems all the rest of the 7 hour drive
back home, even getting stuck in some stopped traffic twice in WI. by this
time it was cooler outside, and I noticed when we were sitting in traffic
that the front radiator fan was running and cooling the van.
and yesterday, after sitting in traffic and at stoplights in town, van
decides to quit and not restart in the middle of an intersection for about
5
min, then it started right up.
Let me know if I am on the right track here, the van seems to run normally
until the temp needle is just barely over the top of the red light in the
center of the temp guage. usually, the radiator fan comes on about then.
so, I think my radiator fan is not coming on when it is supposed to. and
If
it is not that, is there a way to test the temp II? that one of the few
parts on the van that has not been replaced in the 8 years I have owned it.
or the OX sensor? replaced early spring of 2001. also new last spring
plugs, cap, rotor, fuel pump, fuel filter, and fuel pressure regulator.
thanks for any ideas,
Kim
