I honestly have no idea, and I'm drawing about 17 in hg on my vac/boost gauge. Is that about right? Runs rough on idle so I thought I'd check for a vacuum leak.
I'm pulling 15 in hg. So I might have a small vacuum leak then. I have a somewhat rough idle. I've replaced Oxygen sensors, cleaned the MAF, and that really smoothed it out, but its still a little rough. Vacuum Leak a likely culprit?
