a while ago i posted a thread about how my car idled at 3k, long story short it turned out to be the isc valve so i unplugged it and the car would idle at 800 and as the car warmed up the idle would go up to 2k after it fully warmed up. then i took it out for a long drive and the cars idle would go back down to 1k. but ocasionally the idle would start bogging down to 100 rpm's and id have to tap the gas and the idle would go back to normal. what i'm wondering is if it's my pfc that needs to do the idle learn process or if its something else.
my mods are:
greddy fmic
trust airinx intake
apexi pfc
hks cat back

 

please help. bump

 

#1 you need to properly adjust your idle and properly set your Throttle position sensor.

#2 Do you have a dataloggit? Check in your settings menu and tell me your F/C values there will be 3 of them.

#3 Before you do all this make sure your throttle cable isn't binding.

 

ill adjust my tps, i've got no dataloggit :3, and my throttle cables fine

 

the idle learn process is mostly for cars with the ISC functioning.

i highly doubt you will solve this problem without a datalogit.

 

man.. where would i go to get a datalogit. also, im getting a new isc.
