Alrighty im completly stumped. So I just swapped a 99 Gsr motor into my EH3 and never had a problem like this before! Im throwing two CEL's and they are code 41 and 14.

41 beings primary o2 sensor and 14 being idle air control. O2 not a problem at all running open headers right now because single cam pipping was too short so cancel that out.

Now for my code 14, changed 3 IAC valves (one brand new) and cleaned and reseted my ECU and still the code come on and wont go away! I have checked all the plugs are all plugged right and dont know what the hell is going on! and on the back of the manifold there is a vaccum the only way that the motor will hold idle is if that is open. this is a stock 99 gsr motor what the hell is goin on anyone know let me know!\ if you experienced this problem

 

anyone?

 

i had this problem when i swapped in my gsr. i know its an easyy eassssyy fix prob can do it yourself but since i was already at SPEED FACTORY (in tacoma, wa and i noticed youre in seattle) ricky just adjusted something and it was normal..i forget what he did..but easy fix. and i was running open header for a bit too LOL sounds like my probs when i swapped it..and i know one was cus i was missing my o2 sensor. and my ecu grounds were all [freak]ed idk so many probs

but take to speed factory if anything! (yes my *** is promoting cus theyre reallll good) lol and they dont charge up the bootay

 

hmm.. probably messed with your throttle screw on your throttle body. tried that already! but maybe it is my o2. damn.. thanks!

 

pooper :[ lol

 

haha yeah thanks though
