MY GS350 will initially idle at (about) 1600RPM when I first start it up after having it sit overnight. It'll stay at this RPM for about 5-8 seconds and then suddenly spike to about 1900RPM (these numbers aren't exact as I don't really recall what they are, really) and slowly decline as it warms (if I let is sit there and warm up, which is rare).

My question is, does anyone else's 350 do this?

 

going to start my car soon, will let you know tony

 

Thanks, Henry!

 

this is normal for me in the winter*

not sure what temperature will cause this, but usually anything below freezing and the RPMs will spike until the engine temp gets to 40%.

I keep my car in a garage and it still does this, so I can only imagine how bad it may be for people who park outside when it's cold.

 

Yeah...I live in California and it does this daily. It's always park in the garage too.

 

I have an 06 3gs and it does the same

 

Good to know! Thanks!

 

yea its normal, i made a thread about this a while ago.

 

It spikes up and down a bit around 1200-1500 for the first couple of minutes, then a few more minutes of driving it stays around 1000, and when fully warmed up settles at around 600.

 

yup mine too

 

Thanks for the input fellas!

 

well i guess my home is very warm? i just did it this morning and nop. once started, it went up to 1400 rpm, and just started dropping from there to 1200rpm after about 30 secs. today is a cooler day in cali already, and come on tony, we live pretty close

 

Hmmm...since everyone else chimed in that theirs does what mine does, maybe there's something wrong with yours? LOL

Very odd.

 

oh crap you are right! i am taking my car apart tonight and see what's wrong

 

I believe my rpms are around 1600 and then drop down after about 10 seconds to around 6-800 rpms.
