Hello, I was hoping somebody could help me out with this problem. I have an Euro R complete swap in a EK hatch. I'm having some troubles with the idle. When I start my car up the idle goes from 2000 to 3000 rps over and over again.

I have a s300 ecu and its tuned without the IACV. The IAC duty cycle is completely decreased. So I'm sure it shouldn't have anything to do with the IACV. Its been tuned like this for over 6 months without a single problem until now.

If anyone has any suggestions or has any further information. It would be greatly appreciated.

 

Sounds like a vacuum leak.

BTW, how is fitment with the Euro R in an EK chassis? Are you regular H22 transmission, or H2b?

 

I have the Euro R transmission. Fits pretty good, other than my axles are angled a little funky.

 

I meant like how much space do you have between the back of the IM and the brake prop valve? I am looking to do this swap, but I do not want to run into clearance issues like I did with a skunk2 IM.
