High RPM on crank up

Hey all,
I've noticed that when I crank my truck, the RPMs go up to about 1000 and stay there until I put it in gear. When it goes into gear, the RPMs go back down. This just recently started (or just recently became noticeable).

Any thoughts/answers would be greatly appreciated.

Thanks!

 

Perfectly normal.

 

Ok gotcha - thanks for the info y'all maybe I just hadn't noticed it before. Thanks again!

 

Pretty much par for the course for every moautomobile I’ve owned, at least the ones that were reliable.

 

It’s cold this time of year. That’s why.

 

My assumption is that it is trying to increase oil pressure and/or raise the engine temp. It might also be related to keeping the engine running during a cold startup semi related to the air/fuel mixture adjustment a choke has.

 

Normal. Rpm will also drop on its own after a few min .

 

Cats warm up

 

Ah perhaps. I heard they they don’t work well cold. It’s such a short period of tone though. Cloud that much pollution get created?

 

Whatever they have to do to meet emission.

 

I noticed 2016. Throttle body ever been cleaned?

 

Totally normal for any emissions equipped vehicle post year 1990. If it idled at a lower RPM at start-up, then I’d worry.

 

Agree with everyone else. My truck has always done the same at start up.

 

Normal. Also if your foot is on the brake it will increase rpm due to the electronic brake booster on the off-roads. Mine will run about 1300 on cold starts with my foot on the brake until I let off the brake.
