'88 Ranger stalling problem

I've got an '88 Ranger, 2.3L that has developed stalling problems.
The truck will idle in the driveway smooth as a kitten all day long.
When I pull out on to the road, it will begin to lose power and stall.
If I pump the gas pedeal (although it is fuel injected) it will
sometimes keep it from stalling all the way and recover. Sometimes,
it will run a mile or two, sometimes not 10 yards. Doesn't depend on
vehicle temperature or weather. I get no error codes from the
computer, have replaced both fuel pumps, fuel filter, fuel pump relay
and O2 sensor. The coil, distributor, plugs, wires, and idle air
control solenoid all are within specifications.

Any ideas?

Re: '88 Ranger stalling problem

That sounds EXACTLY like what I just had with my 96 explorer. The codes
were reading low signal input to the MAF, and intermittent signal to the
MAF. The symptoms were identical to yours. In the end, it turned out to be
an electrical problem, one of the wires between the MAF and the computer was
broken somewhere along the way. Once I had someone at Ford locate and
replace the wire, all was fine again.

Hope this helps

re:'88 Ranger stalling problem

Interesting. My Ranger predates MAF, but it could be a wiring problem
somewhere. I'm starting to think it's not mechanical, but an
electrical or sensor problem somewhere. Of course, those are the
most difficult to locate. I'm pretty good with moving parts, but not
moving electrons.

Does it seem to have a dead spot right off idle, so for instance if you gun
it it will go just fine but if you drive normal it will cut out/try to
stall? If so check the TPS sensor.
