yo whats up techs need some help here i have already searched. now here we go. i turn the car on and idles up to 4000k plan and simple. i check my timeing flywheel and crank on tdc and skunk 2 cams on tdc new timing belt and balncer belt. becasue it would just rev limit at 4k then i saw oil light. so i changed my oil now i can go to 8 grand no probm just high ass idle. i know that cant be the problem. now i was getting the code 16 which i already searched and says fuel injectors i have the honda servie manual. i took care of that issue. one of the wires from my resistor box came loose. okay so that problem is takin care of. but the problem im having is the idle. now people said they fixed it with iacv well in mycase i have perfect working ones i clean both with the diy form in here still same thing.i dont have a fiv(fast idle valve) becasue i have skunk2 intake manifold 78 mm bore and blow tb that take out the fiv so i know i cant idle it down only if i had that now my set up is this

sounds like you have a major vacuum leak.

Possible problems:

vacuum leak
gasket leak
cam timing off
ecu in limp mode

gasket leak? how i have not drove the car i have the hondata intake gasket the plastic crap and i made sure its bolted down no other spots for gasket leak really .

cam timing. well i set all timing based on honda sevice manual

ecu in limp mode possible but how can you tell that also how could you fix that? thanks fir all the replies im still looking into this also

okay update for those that fix the problem and not say whats wrong well im not like that here i fixed the issue

okay i got another harness and pluged everything up and changed iacv now i dont know if that was the issue but while i did that i noticed the tb plate was open just a bit. how did that happen i dont know damn blox tb. so i saw a screw that positions the plate and i took the screw all the way out. and i also loosen the tps and moved it. and now i got it to idle at a wopping 568 from what hondata smanager is saying lol to low now im cool so for those who have this issue check the tb plate or screw i thnk its an idle screw. and dont worry about the iacv becasue it still idle high. now on my smanager it says the tps is 2% should i get it to zero or is that okay because now the idle is to low.

thanks for all your help and i knew no vaccum leak could cause 4k idle not unless it was multiple.

and it was not my cable because it was to loose

The Skunk2 Manifold has several vacuum ports so if you did not plug one it would cause a high idel.

the TPS should read 0% if its reading 2% its out of adjustment. lossen the 2 bolts/screws and move it into proper adjustment. if you leave it will read 100% when its not at 100%
