hey guys i got my 240sx the other day, and i noticed that when i start it up when its cold it idles at 1900-2000rpms, is that normal? its a ka24de motor.

 

It will idle higher when cold but mine usually idles at around 1100rpms not nearly 2000rpms What does your car idle at when its fully warmed up?

 

my car idles at about 1200-1400 rpm when i start it cold...and I live in North Dakota, where temps are usually about 0 deg. in the winter...and usually, it will not idle there for long, just till the motor get some oil movin through it, then it will sit at about 1000 rpm for awhile till its fully warmed up.

 

strange dude my car idles at just under 1000 rpm strange as it seems the different gas i use the different it idles at when start up and i live in just as cold an area dude...

 

hhmmmm well i still have alot of work to do on this thing, i saw where there were 2 vaccum lines that had been cut just laying there, it just had an enging put in it before i got it, so im going to have to really go through this thing and make sure everything is hooked up right
