Air Regulators again!

[Bazelinez]

Just took my air regulator apart and the spring was loose. Cleaned it all up and put it back together, now its idling very high, like 2000rpm.

Is the regulator supposed to be open or closed once the engines warm? The spring looks like its supposed to be holding it closed but it was half open on mine.

Has the spring had it. Anyone know how much a new AR from Nissan is? Is it the same as the Rb30 etc?

Need help urgently.

chees!

Okay I fixed it.

I ditched the factory spring cause it was stuffed and replaced it with another thicker spring that holds more tension.

The result it it idles up fine but once warm drops straight down to its normal idle, no wandering or anything. Worth the skinned knuckles and abuse.

In the process though I managed to lose both screws that hold the regulator to the manifold. Such a prick to get in cause it can't be reached. Have to remedy this as only one bolt is holding it in....

happy camper!
