I do not know if I still have a vacuum leak, but I do not hear any hissing noises...where can I look for leaks?

I may changed out my VANOS with the one on the site in the future...I have learned to live with the tin-can rattle as my UUC LTW flywheel rattle is louder...but the car just dying when out of gear and turning the steering wheel to pull into a driveway is killing me....also sometimes when coming to a stop...happens in warm or cold weather.
Your idle problem might be the DISA valve. Here’s an informative link.

Take out the DISA valve and inspect it. Try to catch any broken parts as you remove it. If not broken, spray it with break cleaner to clean off all the gunk.
See if this helps.
