Why does my car idle at 2000rpm and after like 4 to 5 min. it idles at 1500rpm... i dont get it... does anyone have any idea how to stop it... i've tried touching the screw on top and that doesnt help... and i was also wondering if it could be the BAC or something... if u got any idea post back....

 

that is normal i believe. a car works harder when it is turned on which is why it idles at 2000 rpms, but when everything is working and down to normal operation the car can idle down because not as much power is need to run the equipment. just saving you gas

 

im having the same probloms....there suposed t oidle at 800 rpm and i cant figure out how to fix it

 

well now my car doesnt idle no more.. its weird cause everytime u put something new to the engine the car starts to idle but... i think its just the car... just drive it for a few days then i think it'll stop idling....

 

turbo or N/A?

 

mines a n/a 1986

 

My 93 Idles at about three thousand rpms for the first minute I start it when its cold. i always thought something was wrong woth it but then it goes down in between 1500 and 2000 rpms. When i start it you can also here the turbos warming up. They shoot out about a minute of high pressure air as well. The problem i have is when i stop at stop lights and once the car is warmed up it idles too low. sometimes it barely stays to where it can run and there have been a few times its stalled. Do you think this is just an idle problem i can fix or should it go to a shop.
