Hey guys, I don't if have real problem or just being paranoid. This started about 2 days ago. Before my car would start the warm up procedure at 1600 rpms, now it's 1900. It does go down after 2 minutes. It has been around 60 degrees outside. Any help would be deeply appreciated.

 

Vacuum leak? Open the hood and listen for hissing, spray carb cleaner around suspected cracks if idle increases there is your problem

 

1600 is even high. It should be around 1200. Check for leaks like it has already had been stated.

 

Time to clean that throttle body build up of thick carbon

 

I agree with this.

 

Thanks for all the advice.

 

start and warm up rpm is dependent on temperature.

Generally, it'll idle higher when colder outside before settling at the same warm idle temp.

 

its an old car. old cars do weird things. this is normal. on a cold start they normally idle high. mine sits at about 1500rpm for about 2 minutes too. mine has done this since I got it 3 years ago. no worries. and yeah I get a little paranoid about mine too. even though its been 100% reliable, Its getting too old to trust. I get it man.

 

Over the 13 years that i have owned my car no matter the temp that start up idle has been 1200rpm.
