Hi guys.
i replaced my spark plugs yesterday. my idle RPM use to be 500 but now i have 1000 RPM. i did reset ECU (unhooked the negative side of battery for about one hour).
new spark plugs are Iridium IX and old ones where OEM.
any idea? or should i be worry?

is that an idle when your engine is warm or when it is cold, if its warm that something is wrong, but if its cold than its perfectly normal

idle should be 650 (+- 50) says the service manual after ur car warms up

it is when is warm. idle actually is 1200 RPM right now, and the exhaust gas smells really bad.
when i was replacing spark plugs yesterday, i also cleaned inside throttle with carburetor cleaner.
is it possible that damaged something? oh, and i toke it to advance auto part(because check engine light is on) and computer said high idle speed.

reset your ecu via the pedal ignition trick then see how it acts, if its still a problem take it to nissan

O.K
i just fixed it!!!
it was my mistake. when i was reinstalling the throttle, i put the brass gate upside down.
anyway, i just wanted to let you know what was the problem.
thank you for your responses.
