A vacuum/boost guage would be nice! The crazy thing about that vacuum cap on the tee, it was the first place I started looking. After hours/days/weeks of removing parts & searching vacuum hoses & lines for leaks and replacing suspect parts, I found the uncapped nipple. A week later the code reset and I found that the new 1/8" rubber cap was gone again. This time I applied a little glue and another new cap. Klaus, if vacuum is negative pressure, could/does the turbo boost cause positive pressure and "blow" the rubber cap off? It still runs great, 26mpg, idles smooth, no problems. Just wondering!
