Re: Car shuts off

Off topic,

But back in the early 70's I had a problem with an old Chevy panel truck
that drove me crazy for six months. I bought the old Chevy from a fellow,
cheap. He warned me that it would not run below 1/4 tank of gas. Sure enough
he was right. I found it would stall at a little less than a 1/4 tank
showing on the fuel gauge. I could restart the truck and run a short way,
but it would stall again within a minute. When I filled the tank everything
was fine until I went below 1/4 tank again.

Over time I replaced everything in that fuel system except the gas tank to
no avail. When I finally pulled the tank there was a ping-pong ball in the
tank that apparently would get sucked up against the fuel line when the tank
got below a quarter full.

Bad MAF or O2 should throw out the code but not kill the engine. The ECM
should be able to overcome that so the engine can still run (though rough
or dying). I would still suspect electronic issue.

I had two cars in the 80s that they died at the certain engine temp. After
I got stuck a few times, I could even tell when it was going to die just
by looking at the temp gauge. Once it cooled down (in about 15 minutes),
everything was fine. I had to carry my tools to diagnose the problem on
the road! In both instances, the solid state electronic spark control
(not computerized yet) was at fault.

Alright, I reviewed all the discussions in this post. Go to Autozone and
rent out their OBD-II scanner... It plugs to the underside of your
steering column... there is a cover there that said OBD-II.

Read the codes with your ignition on but engine off... see what code it
puts out. It probably would say O2 sensor or fuel mixture lean...
something like that. We need to find out which.

If that scanner has O2 tester... that reads out engine RPM, the readings
on the O2 sensors, that would be great so it would tell me if O2 sensors
are good or bad.

I have a feeling it is probably either the MAF or the O2 sensor that is
bad.
