Rough idel when cold
My 98 deville with 131,000 miles started to run rough when you first start it up in the morning then when it warms up it's fine, so i don't know if i should change the plugs and wires to see if that dose the job or if you guy's can think of anything that would cause this. Thank you.

rough idle is probably due to fuel, coil, or intake issues.
pull codes and report back.
