ok a lil info to start i own a 2005 350z base model im about to turn the grand old corner of 80,000 mile yikes i understand my car is getting up there and is at the point i should start expecting issues which is why im currently restoring everything worn or old on my car soon with an N/A beast

ok this morning i started my car and for the seconded time going from work to get some breakfast and i noticed when i turned it on it idled at 2000 rpm something a bit odd, because the highest iv ever seen it idle was at 1200 on a cold day till she warmed up, she took forever to go back to normal around 750rpm but it took flipping forever after pulling out i was in second gear with my foot off the gas my car kept moving on its own because the idle was so high

well after driving around and putting it in neutral(right outside the parking lot) it slowly went back down to about 900 rpm which is higher than normal
its continued to do this even on warm or hot starts after sitting for a bit

my friend said something about an idle limiter sensor gone bad but im not sure if that even exist in my car
so can someone help me and tell me what up with my car weeather=i can drive on it or a while or is it something that needs to be replaced asap

 

Been seeing these kind of threads lately.
Maybe just because weather is changing??

 

i doubt it iv had my car for two years and never seen this and it was only 60 degress outside vs iv started it in the low 40's without a prob

 

anyone else with helpful info

 

MY 07 idles at 2k rpm for a few seconds during start up since the weather has gotten colder. Warmer months it at 1K at start up

 

my friend said it was the idle positioning sensor any idea what that is

 

today my car started at 1800 and I am in socal.

 

maybe the weather is colder?


my start out in the morning around 2000 rpm.. and went down to 750rpm..

i am living in san diego.. but my idle does change as it get colder tho.. i noticed that a long time ago.. but didnt really care.. thought it is normal.. heheh

 

its because of the season change
