First the details:
1991 honda civic dx automatic
1.5 L engine
126,000
The car was starting up fine until last summer. Over time, the situation has gotten worse. My dad suggested that before I turn it off, I floor the gas pedal till the engive revs high, then turn it off at the peak of the rev. And that worked! at least for getting it started first thing.
But it did not solve the problem -- because in the last couple months, the engine is worse. First, when I brake/stop and then start going again, the engine sometimes stalls and I can sit there cranking and cranking--with it sounding like it is almost ready to catch -- but not. Here are some examples.
1.Sometimes, I crank and can hear it begin to catch, so I release the key and it dies.
2.Sometimes it begins to catch, and when I release the key, it continues to run/idle but so quiet, I can hardly tell it is running -- when that happens, and I press the pedal down, it dies.
3.When I get it to start and drive, if I stop at a light, it continues to idle ok -- until I press the gas pedal, and then it misses and sometimes even dies.
4. Or when I stop and then press the gas pedal, it misses before it starts moving -- with very slow acceleration.
5. Once it is moving, there is no problem and I do not hear any missing.
When I park and turn off the engine after I super-rev it like my dad suggested, it starts right up again. These problems are only when it stops without that rev, and I have to restart it.
The shop put in a new fuel injector and I had the timing belt/transmission tested--all okay.
Help! what is causing this?
thanks,
rambelmont

First of all, revving an engine like that without any load on it is the worst thing you can do. You can easily blow it up.
You may want to start by checking fuel pressure, cap, rotor, wires, plugs, fuel filter. If all of these check out ok, perform a backpressure test to see if the catalytic converter is clogged.
Please post back with the results.
