Well, I guess you could say it was an experiment that seems to have gone wrong. On a whim, since I had 2 blow off valves on my car, I decided to T off the vacuum line from the UIM and run 2 blow off valves, for ***** and giggles. Since I have done that the car has been rattling like hell when idling but running strong once I hit the gas. It feels like something was knocked loose but it coincided directly with the modification in which I did not noticeably knock anything loose.

So I removed the old Apexi BOV and opted for only the Greddy Type S. I have it flanged at the elbow and it is a very tight fit. The top screw bites into my strut tower.

It seems that it is running rich and the only time it even idles rough is when the A/F reading is richer than 10:1 or even up to 14:1 at idle. I think I remember at idle before this the reading was past 20:1. Could this be it?

So, besides being an idiot for trying 2 BOVs what could the problem be?

check to see if the bov's are opening at idle... if so you need to tighten the valves so that they dont open.... cause when they are open at idle you have a vacuum leak the size of a golfball and that can make your car do all sorts of wacked out stuff.

(i run two blow off valves and it works fine)
