Hey guys, well heres the problem.

Today i installed a skunk 2 intake manifold, Aem Fuel rail, Injectors, and Fuel Pressure Regulator Onto my d16y7 civic.

For the most part everything seems to be connected correctly, i had a hard time getting the car to start but after switching some sensors and hoses i finally got it to start.

Now that it has started, my engine revs up high, almost 4,000 rpm, then comes down to like 1,000 rmp then back up, and so on....

I dont know what the problem could be, anyone have any ideas?

I kept the stock throtle body for the d16y7 and just adjusted the spring to fit on the manifold, and blocking of the IACV port in the back of the IM. I did this because the y7 has the IACV on the Throttle Body itslef, so everything was pplug and play.

Please guy help me out, its my daily driver, i need her

 

Air bubbles? Try bleeding it bro, what ever you do though, dont adjust the idle screw cuz the problem will still exist. PM me if you need help on doing that.Oh and double check to see if everything is connected correctly, like there isn't air escaping from the skunk2 manifold..

 

I would check for vacuum leaks to start, otherwise it may be something with the iacv as when they are bad they like to "hunt" you could try cleaning it out and putting it back on. other than that I would make sure everything is plugged up right.

 

thanks, guys, its working now. now im just having a problem with the cooling system. The car doesnt get hot but the overflow tank keeps bubbling up and spiting steam out, any ideas?

 

anyone? come on guy, i need to go to school tomorow :/

 

did you "burp" the system? if not, when the car is cold, take the radiator cap off and let the car run until the fan kicks on and you dont see any air pockets in your coolant.
