My mechanic tells me I need a new airflow meter, and he has been looking
around our island (Saipan) for a used part. One of his workers pointed to
a piece near the throttle and said that was the air flow meter. I could
easily be wrong, but I think the part he was pointing to is the throttle
position sensor. Could you tell me where the airflow meter is and what it
looks like? Thanks.

92 Excels in the U.S. have a fuel injected 1.5L Mitsubishi designed engine.
On these vehicles, the air flow sensor is inside the air box and has a six
pin connector.

My model is actually a Korean domestic. I don't know if the actually engine
is different or not. I do know the air filter is different, so some things
are not the same. Is there a chance that the system does not have an air
flow meter? (That's what one guy at the parts shop said, but that is taken
with a grain of salt.)

Thanks!!

After doing much research on the Internet and some poking around under the
hood, my latest theory is that it is not the air flow, but the throttle
position sensor is not adjusted correctly or it is faulty. I've read that
the sensor is very sensitive and needs to be adjusted using a volt meter.
I've asked around on island, and no one knows how to do this. Do you know
the specs for this, ie. voltage readings for open and closed? Is there a
way to tell if the sensor just needs to be adjusted or replaced? Any tips
for hooking up a volt meter would be much appreciated (ie. which wires,
etc).

Thanks in advance!!

By the way... I live on a small island and the local mechanics have all
tried, but simply are not familiar enough with Hyundai's to fix this
problem.

It is now in my hands... I am mechanically inclined, but NOT a mechanic.
Any details you can offer are very much appreciated.

To give you a little history of the problem... after warming up (and often
when going up hills), this 92 Excel stutters, and almost looses all power,
but not all the time, maybe 75% of the time. At other times it seems to
surge. Spark plugs, cables, idle control, fuel filter, and oxygen sensor
were replaced, and the throttle body was cleaned. The symptoms have
continued.

One mechanic said the Air flow sensor needed to be replaced and he pointed
to the throttle position sensor. This got me thinking (after I found out
what it was), and I blindly adjusted it. The symptoms did not change in
nature, but were markedly different. The next day, I had another guy look
at it and he adjusted the throttle cable. Again, the symptoms persisted
but worsened. This leads me to believe that this sensor is causing
problems and possible the root.

Thanks again for your help.
