I was running -.5 Bar at idle on my sr20det but now my gauge is reading -.62 to -.9. I don't notice anything different, I don't think its my gauge or if there is a leak because if there's a leak in my gauge line because wouldn't there necessarily be less pressure? The only thing I can think of that I did recently that might effect it is that I cleaned the IACV with carb. cleaner and changed the coolant temp sensor. Also, It does not jump around. Its a steady reading. Average at idle, 850rpm, is -.72ish Bar.

Well if you think there's a leak...then check for leak. Its always a good idea to check for leaks every other month. You'd be surprised at what you find.

From what I could see/hear there are no leaks. My valve cover bolts had gotten a little loose, tightened them but it didn't change a thing.

-.72 bar is within spec.

-.5bar seems a lil high, -.62- -.72 seems about right

Well I guess I "fixed" my problem then. It used to be at -.5 Bar...
