Setup:
00 GSR Stock engine
Blox Intake Manifold
t3/t4oe 57 trim .63 a/r turbo
Log Manifold
Hondata s300
ngk brk7e spark plugs
ID 1000cc saturated injecters

The car had the head milled since it was warped from overheating, and the HG was replaced with a OEM headgasket, while the head was off the blox manifold was put on the car and this is when it all started.

The car was tuned before the HG was changed and the intake manifold was the only thing changed, I messed with the IACV settings in hondata and it seems no matter where I move the slider there is no change in the idle or any type of response from the change.

I unplugged the IACV and the check engine light came on as expected, but no drop or increase in idle. After that the IACV was replaced with another one, although it was not a brand new one it. I also put my hand over the throttle body and the car died, so I dont think the car has any type of vac leaks.

During idle the cars A/F was between 13.7 and 14.4 but never left outside that range and once the car gets going the car runs fine, however at idle or slowing down to a stop and when the clutch is pressed in the car will die. Hopefully someone else will have some other ideas because I am stumped..

Thanks in advance.

 

The 2000 gsr throttle body is still a cable throttle isn't it? If so tighten the cable. If that doesnt work your timing on the distributor might need to be advanced.

 

it may need to be retuned a bit.

 

Is it alright to advance the timing at the dizzy because hondata says it should be at 16 degress in the software??

It is a cable throttle body, I am guessing tighten it so the throttle body will be open a bit at idle correct?

 

The afrs are good for idle...the IACV slider is not responding to anything, what else could be done to tune it?

It is supposed to be retuned later this week although I have a feeing this is some mechanical issue not a tuning one because none of the idle options seem to affect the motor...

 

That was my idea with throttle cable. Im not sure what hondata says about the dizzy timing, if they say it needs to be at a certain spot then dont go messing up the timing. Dont want to tell you to do something wrong.

 

Blox throttle bodies and intake manifolds are none to leak some various spots, do a boost leak test and make sure nothing is leaking out of the intake. We had a customer that installed a blok throttle body and never could get it to idle right after that, after doing a few test, the thing was leaking out of the tps shaft and throttle rotor shaft.

 

Its a stock throttle body, but ill try what you guys suggested abd report back. Thanks for the help so far!!

 

Still could be leaking some where else on the intake manifold, I.E fuel injector seal "aear"

 

did you use the correct TB gasket? if the IACV is not responind to any changes, then its just not getting any air to it. also, check the port that leads to the iacv for blockage, maybe yours has a casting flaw

 

Its the same gasket that was on the TB..I blocked both holes and nothing, but do I need o try both each or both of them at the same time? I covered the TB with my hand and the car did die.

 

there should be air going through the hole on the inside, if not, then you port is blocked or the iavc is not opening at all. If you have swaped iavc and it has a cell when unplugged, my guess would be a blocked port.
Take the IAVC off, blow some compressed air in the side port on the TB to see if air makes it out of the hole on the back of the mani,

 

You are a life saver, the iacv port is clogged up with some kind of dirt ****...its a pain in the *** to get out but at least the issue is solved!

Thanks again and hopefully if someone else is having a issue like this they will find this post and it will help them.
