hey guys, i just finished bolting my d16z6head onto the d16a6 block. everything went smooth as can be.. but for some reason when i turned her over for the first time it was idling at 4000rpms. i immeadiatly shut it off... anyone know what could be causing this.. this only difference in the setup is the vtec head.. everyone thing else is the same..

head was p n p as well
d16z6 head on d16a6 bottom end
skunk2 high comp valves
n1 catback

 

Check all your vacuum sources. Make sure they are all hooked up.

 

theres one hose unpluged and thats the one that hooks up to the valve cover.. i dont think it would make me idle that high... i just used my stock intake mani and exhaust mani with the z6head.. is it bad to run it at that rpm? new valves and all? i lashed them to .008 on intake and .010 on exhaust

 

that hose to valve cover is probably the breather hose, which don't worry about really... only worry before you get car smogg'd or if a cop lifts your hood. hook that hose to intake later or whatever. i have to jimmyrig 2 hoses together tightly to fit lengthwise from my valve cover to intake. check your IACV, when mine wasn't hook'd up it was idling all weird too...

I'll edit and post a picture in when i get one in a second.

 

so what could be my problem for this high idle???
could it be timing problem? i did everything by the book. trying to get some othering input before i got dicking around with it... could the 4k idle hurt the engine? and its also smoking bit out of the tail pipe

 

IM gasket.

 

check that throttle linkage

 

That would be the first thing to do. Check your butterfly in the throttle body when the car off and on. See if its open at all.

 

throttlecable isnt the issue. butterfly opens full throttle doesnt stick.

goin outside to check all my connetctions in few

 

double checked all connections,everything is exactly the same... the tb and im both were fully funtional on my vehicle before i bolted on the vtec head....running stock ecu injectors dizzy, eveything same except the addition of the vtec head.. i also bleed my coolant and a big old air bubble came out... i havent started it up yet again.... is it bad if i drive it with a 4k idle lol....

 

4k idle isnt good, you'll be burning up gas like crazy. and you said you had smoke coming out the end so you wont want to drive it that far if at all.


good thing you burped your radiator too, I didnt do that (forgot too when I swapped my engine) and after about 4miles my temp gauge was red lining, had to figure out what was wrong real fast hahah.


all connections might be connected but are they correctly connected
