Ok so I have a d16 turbo and I have it tuned. For some reason since I had the shop replace my tranny, whenever I rev the car high and let it idle, it drops below 1k rpm and wants to stall. It drops to 100 or so. I dont know what the problem is. I tried cleaning the iacv and nothing. What cat he problem be?

 

Is the CEL ON? Can you retrieve any codes from the ECU?

 

no cells whatsoever

 

Have you tried adjusting the idle screw on the throttle body?

 

ill try that. it idles fine until i take it into the higher rpms. then thats when it wants to die.

 

Adjusting the idle speed is worth a try, but it really sounds more like an IACV issue. Also, limp mode is usually associated with a CEL trouble code, so I am puzzled by why the ECU would default to this mode.

 

its funny my stock d16 does something similar. At normal operating temp, If I just sit there and rev it, sometimes it will drop all the way down to 200 - 300 rpm and choke a little. Hopefully someone will help you with your problem!

 

Well I dont know exactly if its going limp. I do know that it wants to die after revving it high. Maybe Ill try changing Iacvs. Can it be the tuned map?

 

any other suggestions?

 

my d16 would do the same thing i changed the plugs wires n distributor n it was fine

 

hmmm my wires(Oem) and plugs(NGK V-power racing) are almost brand new. Maybe the dizzy? Igniter or coil? Ill try that

 

cool, keep us updated please!!

 

fixed the vtec solenoid ground disconnected

 

hmm so this was all cause by a bad ground for your vtec solenoid how would that affect idling? I have a similiar problem it only does it when it is warmed up and it doesn't do it all the time. Only when i don't have time to mess around with it, or if it is raining or something ha. But i know my ground is good i was really hopin it would turn out to be something else i guess there are alot of things that could cause this

 

yeah im guessing whenever i try and hit vtec it doesnt engage or something. then it idles weird and sputters and what not. it sucked because i would have to restart the car for it to idle normal again
