rough start-up diagnosis ??
car: 96 civic dx (STOCK)
symptoms: car starts with hesitation and idles rough. it had a cel 71 and 72 (cylinder 1 and 2 misfire).
so i check the plugs, distributor, coolant was a little low (i went ahead and topped it off) but oil level and condition was good also (not milky).
i then reset the ecu to see if it will still throw a misfire code. start it up it only slightly hesitates for a second or two then idles and drives fine. no more missing/hesitation and no cel. basically it only hesitates on start-up
what can cause the car to hesitate on start-up but then drive fine?

Re: rough start-up diagnosis ?? (SINFULintegXsi)
anybody?
i noticed when its warm outside like today..it stumbles when trying to start. (as if there wasnt enough fuel) i would have to give it a little gas to help it start.
im going out to get a fuel filter, new spark plugs and wires (cap and rotor look fairly new) and see how that goes

Re: rough start-up diagnosis ?? (SINFULintegXsi)
swapped out the spark plugs and fuel filter..started up fine but the symptoms are usually when it has sit for a little bit..so im taking a break and seeing if it'll start right up later.
i noticed the valve lash must be off because they are ticking louder that i think is normal, can this be another possible cause for rough starting?
