so i have a 96 civic hatchwith a obd1 d16z6 swapped in it. ive replaced the o2 sensor, plugs, and corrected the timing. basically my problem is it will randomly just turn off. i think i recall 2 clicks from the dash that makes me think main relay. but also today twice within 30 ft crusing the dash guages went to 0 then back to normal and i heard the 2 clicks. its very wierd when it happens and normally just stalls when i just start it and it idles for a minute. also when it does stall sometimes it wont start no matter what and i have to let it set for 20 mins or so and then its fine.

 

check your grounds.
