ok just swapped a d16z6 into my civic. it has a erratic idle jumps between 1000 and 1500 rpms, i try to accelerate and it seems to have no power. i disconnected the iac to adjust idle rpms and seemed to have no effect to it when i turned the screw. noticed a little white smoke coming from cat but am assuming its just dust since the car sat for about a year any help or suggestions? oh and have a leak in exhaust so can't hear if vtec is coming on or not

vac leak? spark?

Have any Cels?

ok problem changed slightly.
i had 1 and 2 wires mixed at the dizzy.
now it still bounces at idle and it has too much acceleration it jumps to high rpms as soon as i shift i was doing 55 or 60 in 5th at 6500 or 7k rpms
any help

Check to see that you don't have your IACV and IAT connectors swapped.

thanx i'll try it

i'm not sure thats the prob forgot to update vtec is working and if the iatc valve was switched vtec would be off correct?

cloudconnected85

switched the wires didn't help check engine light came on
so i think everything is hooked up right.
pulled off iacv it looks ok the screen is clean and everythings connected

under the TB should be two coolant hoses you get them mixed up during hook up??? also check your TPS make sure its adjusted properly, and bleed your cooling sys of any air that might be in it

cloudconnected85

i'll try those also thanks

just wondering if those hoses your refer to really matter if they are mixed up??
where do they supposed to go?
also how do you bleed the cooling system?
sorry for the questions but i'm a noob at this

how did you find the leak?
what product and process?

i used throttle body cleaner my idle was messed up and when i sprayed a little on the intake mani where it connects to the head the idle cleaned up and went to normal until the spray was gone just spray it around the im the throttle body and on your hoses to find out where its at.


now i gotta pull the head cause i think the head gasket is gone

on the block the upper coolant hose theirs a little tit where the hose meets block you loosen it up coolant and bubble will come out the hole you have to do it while its running and has reached norm operating temperature

and yes sometimes those hoses get mixed up and it will screw everything up lol I DID IT ONCE! LMAO

well i swapped the head on it to try to fix it. now the vacuum leak at the im is gone. but i've still got one somewhere else its idleing at around 1500 with the iacv unpluged. and when i swapped the head now my crank seal is leaking oil so i can't realy look for the prob. i will update when i can. but would the fact that the head has only got 200 miles on it since it got a valve and resurface job be the suspect of the seal going out?
