When are you going to bring it over for a pre-smog test to see what the difference is now that you have fixed vacuum issues? I suppose once you test the Cat. out. Remember, when you do, to drive it around just before taking the temp measurement.

Had to take a break for life.
Got some vac lines & things coming from Pelican.
Need to call to see if they have larger black rubber line in meter length.
I tried to test out the tg on the Volvo.
Had it just idling so it wasn't so hot.
Exhaust pipe coming out of engine read in the low 400 degrees.
A aluminum tubung was about 160 & I noticed a small pinhole in it.
I tested the pinhole temp & it was 220.
So the gun was able to find that leak which was hotter.
I'm guessing that the temp gun is working correctly.
I tried to get the temp at the cat & in front & back but I never got temps over 160. The car was not that hot & it was just idling.
I'm going to have to see what I did wrong as I'm thinking the cat should be hotter in the Volvo. I've thought I heard the dreaded rattling a few times so it might be toast. It was replaced a couple tears ago with aftermarket.
I'll have to call around still.
