Its Throwing cel code 14. ICV.
it idles just fine. but wont rev past 3500.
and if i take the ICV of and start it it idles at 3500 like launch control or its hittin rev limit.
cleared the ECU sever times.
dirty ICV?


anyone know whats up?

 

Take off your IACV and clean it real good. Clear the ECU after you do that. If you're still getting code/limp mode, replace it with a known good one.

Good luck.

 

ok. thanks man

 

if you cannot what so ever rev past 3500 then its DEFFINATELY your tps. trust me on this one

 

but its throwing iacv code?

well when i did the swap your suppose to swith the two outside wires on the sensor. i did that. so...

 

something might not be fully connected.. or a vacuum leak somewhere. if u hadnt swapped the wires around then the motor would idle wide open. but im not too sure on what it could be

 

Just check your wires, ecu, make sure everything is connected right.

 

check it for cracks

 

ill try more stuff tonight

 

wht kind of ecu are you runin?

 

I have some sort of the same problem , mine has a b18b1 trubo setup ran fine with my b16 turbo in it but now when you start it for the first 15 seconds you can rev it to red line if you desire but after that it kicks to "limp mode". Throws codes for bad iacv and or bad pcm . I tried different computer and it does the same thing so I'm sure it isn't the ecu . Had this problem once before when I first swapped a ef hatch with an ls drop found a forum saying switch tps wires didn't have a problem since. Iuntil now.

I replaced my tps and map with known good ones webt through my dizzy wiring. And injector wiring. No flaws. Replaced my dizzy twice because it once threw a crank angle sensor code hasn't done it since .

I'm kinda out of ideas besides replacing the iacv , I also noticed when removing the iacv there wass no coolant in thee lines any help is appreciated

 

if there was no coolant in the lines, most likely the iac burnt out.. check the lines for debris causing it to plug the lines and than change the iac.. i know its like 200 but 200$ > 2600lb paperweight imo.. i hope its something silly that you overlooked.. hope all goes well man..
