Hi all:

My car is acting up again. And it is one of those intermitent problems. Could any provide some insight?

Details: it is a Civic del Sol '93 SI, D16Z6 engine.

Here is what happens:
- it starts then, while idling, it stops then it doesn't want to start again; when this happens there is no spark; i checked the ECU codes (shorted the 2P terminal) and the CEL stays on (no blinking);
- with the CEL on, does it mean it is the ECU at fault?

More on this:
- if i let it sit for a couple of days, it works (starts/I can even drive it); but, then, the next day it's up to the same thing (stalls and doesn't start);
- once, it started after i reset the ECU, but sunday it didn't;

Things I checked (w/ a voltmeter):
- batery: 12.56 V alone; 14.4 V when running (alternator running); while cranking it goes down to cca 9.7V (that's when the person cranking stopped; it was about 10-15sec);
- coil: 1.1 ohms primary (a little high; should be 0.6-0.8 ohms but this might be the error in my meter too!), 18Kohms (or so) secondary; within params;
- the coil was changed last year;
- ignitor -- should be fine, I replaced it a couple of years ago;
- checked the distributor cap and rotor; the rotor is a little rough, but otherwise they are fine; IMHO any issues here should manifest every time not once in a while;
- spark wires: resistance within params (I forgot the actual vals); there is no spark w/ the wire disconnected from the spark plug, but when there is I can see the spark!
- cleaned the throtle (w/ carb cleaner) and it worked afterwards, but next day it started/stalled/didn't start again.

Thank you, Neko
