the other day my girlfriend was driving the crx and it just died on her. I tried to start it but it would turn over but wouldn't start, I guessed it was spark plugs and replaced them. It still wouldn't start, so i had a friend who is very good with cars come by and look at it, he pulled out one of the spark plugs and smelled it (after i tried to start it). He said it smelled like gas, like there was a lot of gas. he then showed me how to clear the cylinders after it gets flooded, by holding the gas pedal to the floor while starting it (apparantly this pulls lots of air into the cylinders and forces out the gas). it started right up pouring out lots of white smoke. It has worked fine for me since, accept sometimes it acts just like it did before i new how to "unflood" it.

Any ideas as to what i should work on next? it can't be flooded after it sits all night, can it?

[edit] its a 1.5 liter.
