2002 Nissan Sentra Rough Start
Sentra started running rough/missing for the first 15-20 seconds after starting. After that, it smoothes out and idles fine. No CEL. Any ideas why it would just miss on a cold start?
If it's acutally skipping, you may have a bad coil pack. If it's just a rough idle,I'm going to say it's carbon build up on your throttle body and IAC valve. (Air Intake Control). Buy a can of throttle body cleaner and clean them both. If no idea on how to do it, just Youtube Nissan IAC cleaning. Plenty of videos.
Could be a dripping fuel injector. HTH. - Jim
Leaky injector is what I was thinking. I just noticed a fuel smell after starting it the last time.
Ah, then yes, that'd be the first thing I'd check. Thank you for the best answer click! -Jim
