Mazda MPV Van Repair Questions and Answers
Question: 1993 Mazda MPV mileage:
87,000. When stepping on the brakes for an extended
period of time (e.g., when stopped at a traffic light),
the brakes go down lower, and the anti-lock light and
brake lights come on. This happens intermittently. I
would then tap on the brakes again to make the lights go
away. At least three different mechanics (including the
dealer) checked out the brake system and told me that
there were no leaks and the brakes were in good working
order. The dealer also told me that it was either the
anti-lock controller unit or the master cylinder, but
that they couldn't tell for sure until the problem got
worse. One mechanic checked it out with a computer and
found nothing wrong with the anti-lock system. Shall I
just wait until it gets worse or go ahead and replace
both the master cylinder and the ABS controller unit?
Answer: We suggest replacing the
master cylinder first. It sounds like you have an
internal leak in the cylinder allowing the brake pedal
to sink.
Question: 1992 Mazda MPV-4WD
mileage: 110,000. During the spring/summer/fall, when my
van is warmed up to normal operating temp, if I shut it
off and let it cool down part way, it doesn't want to
start. It acts like it is being choked. If it cools
completely, or if it is still at full temperature, it
starts fine, but when it has had 20-30 minutes to cool,
it acts this way. It will run Very rough, when it does
finally start for about 30 seconds to a minute. Any
thoughts?
Answer: An internal fuel leak,
possibly a fuel injector or fuel pressure regulator,
could be causing your problem.
Question: 1991 Mazda MPV mileage: 75,000. I have a hard
starting condition when cold. In addition, occasionally
the idle is rough, and then the car just stalls, and I
have to let it sit a few minutes before I can get it
start. I retrieved trouble codes 1 (no
ignition pulse) and 3 (No G signal). Do I need to
replace the distributor? I tested the resistance
of the ignition coil and it was within specs. I
tested the resistance of the pick up coil and it was
within limits. What else should I be looking at?
Thanks!
Answer:
Your car may be ready for a major tune-up including
spark plugs, plug wires, distributor cap, rotor, fuel
filter and air filter. Also, perform a fuel pump
pressure test. Clean fuel injection system
including throttle bore, idle speed control motor and
passages. If problem still exists, scan computer
for trouble codes.
Question:
1990 Mazda MPV mileage: 210,000. Our MPV has
a great body, with no rust and a decent interior.
We take a lot of time trying to do good maintenance, but
the engine/trans are getting worn; obviously with that
many miles why not. We want to keep the van, we
really like it... but we've never been really wild about
the lack of performance. I would most likely be
replacing the eng/trans with new ones. I am
assuming, is there any performance gains to be made
anywhere with this combo? I do not think it
has much more than 120 hp maybe 150 torque that just is
not much for this vehicle to have safe passing power let
alone try to tow anything...any ideas would be welcome.
I would also be curious about what improvements could be
made in the braking and suspension departments...I have
spoken with another mechanic and I'm looking to get a
few more opinions...Thank you for the time.
Answer:
The factory parts are designed for maximum performance
and reliability. We would think a “fresh” new
engine would run, power wise, stronger than the old one
with 210,000 miles.
Question:
1994 Mazda MPV mileage: 70,000. Sometimes in
the morning when I go to start the mini van and let it
warm up for about 5 minutes or so, the engine seems like
it wants to die out and shut off. I have to play
with the gas pedal to keep it running. Could there
be something wrong with my fuel system or is there a
vacuum leak somewhere? I hope you can help me
solve this problem and any suggestion will be very
grateful...thanks and hope to hear from one of you guys
ASAP

Question:
1992 Mazda MPV mileage: 94,000. I have a
1992 Mazda MPV. It has a 3.0L V6 engine with
94,000 miles. When I start it up cold, the engine
makes a tapping noise for about one to two minutes.
As the engine warms up, the noise goes away. When
you raise the hood and listen, the noise seems to be
loudest near the valve cover on the passenger side.
The engine does not use any oil between changes (3,000
miles), and is very quiet when warmed up. Is this
noise anything to be concerned about? What can be done
to remedy this problem?
Answer:
From what you describe, you have a hydraulic lifter that
is failing. Replacing it should fix your problem.
