idle rpm question... potential problem?

royaldiamond · 09-03-2016, 07:07 PM

Within the last couple of weeks I have noticed that when I come to a stop a red light my rpms' stop at 650 (which it has always done in the past) but then it will slowly drop down to 550. Is this a concern? Any suggestions of what/how to check any issues.

Just want to correct it now if its an issue, instead of getting stranded somewhere in the future.

thanks.

I noticed my does this whenever I don't have the A/C on. Don't think it's a cause for concern...

Mine does this from time to time. It's not a concern. N54 engines have a personality.
