Somebody please help me understand, My car is running 20% cooler (1 second fix) Options

[jsayre914]

I have been driving my 2056 with D-jet everyday. I am putting about 2400 miles a month on this engine. IT IS FREEKIN AWESOME ! I am very happy with the engine temps, the oil pressure has been right on or just a bit under after long 1hour spirit driving. BUT......

Couple of days ago I heard a loud bang in the front of the car. I pulled over and looked around a bit. Discoverd the sound was the fuel tank, mostly empty had sucked the side of the tank inward a bit. (IMG:style_emoticons/default/blink.gif) It popped back out when I removed the gas tank lid. I also noticed that the tank is always way pressurized every time I get gas, no matter how full or empty.

So I pulled the tiny rubber hose off of the charcoal cannistor (the one to the fuel tank) and put it into the plastic drain hose that exits from the bottom of the car, so no fumes in the cabin. Then I took it back on the road and really opened it up. It ran SOOO much better (IMG:style_emoticons/default/WTF.gif)

3 days later I have noticed most of the bucking at speed is gone, engine temps are 20 % less then they ewre. I can drive 1 hour at 4k and the needle is not even getting to the E in "TEMP"

Oil pressure is now staying high for longer on cold start and then it stays always above the tach (Incredible) the whole ride 3500rpm @ 40psi. I even get 20psi @ hot idle and I have never ever seen that before.

So please explain how this 1 second fix improved my engine performance so well. What do you think the problem was, how to fix, is it cool to leave it as is. I am having one heck of a good time in the rain today

p.s. I did not plug the nipple comming of the cannistor so the line is open, not sure what that does either.

How is this system supposed to work.
