sputtering at low temps cold start
my 96 civic doesnt do it often but when i have not started it overnight and its cold in the morning it sputters at low revs and then revs up after a second or to to warm up, is there a fix or explanation for this?

Re: sputtering at low temps cold start (pjpellici)
Could be the insulation breaking down on plug wires, cap, or rotor?
Try checking it when it's real dark out. Turn off all the lights & start the engine. Look for arcing on the distributor cap & plug wires. (Looks like a dull blue glow.) It works better if the engine's thoroughly cold, & maybe use a windex bottle to spray a little water on it. That's a lot easier than trying to visually look for defects in the insulation.
There's other possible causes, but arcing is easy to look for. BTW, how old are the spark plugs?
