Re: Finding Vacuum Leaks

Thanks Leo, I'll put my booster dedicated to the fitting on the intake, and the pcv to the fitting on the throttle body.

In regards to plugs, earlier this year I was chasing a rough idle. but only on the drivers side. I'll attach a pic of the plugs. My timing was way off somehow and after adjustment it seemed to go away, but still a little rough. I'm beginning to wonder if I should just pull the intake and reinstall with some sealant around the ports for added insurance

Unfortunately didn't mess with the car in the 100 degree heat here in new england. Went offshore fishing where it was cooler
