wat up, i just did a z6 intake manifold swap on my d16y7. it went in pretty good and it was very easy. the only thing is that the car is idling at 4000rpms. need help. why is it doing that?

 

I had a similar problem i just changed IAC.

 

does it only do this when its cold...???

 

You also may have a vacuum leak.

 

thanks man ill see if that will work

 

yeah bro it does it when its cold

 

is your throttle body open?

Check all of your vacuum hoses. It could be anywhere.

could it be that i have low coolant?

 

bump for an answer...my buddy did the same thing on his cx hatch. Always had a high idle before it was warmed up. Never found out what it was, we checked all his vacuum lines too, didn't have a leak either

please help!!!!!

 

check the wires from the IAC. See if the is voltage.

been messing around with the sensors and it sounds like a ******* rotary.

 

Discoonect the plug for the iac and you will need a volt meter. Turn car on and see if there is 5volts. If there is voltage your wires are good.

vaccum leak - make sure you cleaned off all the old gasket material.

throttle cable too tight

adjust idle screw

IACV fix/rewire?

i almost know what it is, your stock intake manifod on the y7 was a down draft pile and you upgraded, and your ecu isn't recognizing the increased airlfow so its idleing high. mine did the same thing only i put a throttle body spacer on. good luck man!

 

Y7 and Z6 throttle body is the same diameter. How will a throttle body spacer affect idle?
