Greetings -
I'm checking a few things on my DD (03 Jetta 5 speed, 355k miles) but am questioning my cat, as performance has started to resemble some clogging. I've had 2 badly clogged gasser cats in the past.
Looking at temps after driving home from work (3 minutes to change clothes), the cat temps were (using HF laser temp):
entrance: 120
exit: 120
cat body: 180
I've been told a couple things with these -
1) it should be hotter behind the cat than in front.
2) the exit of the cat should be way too hot to touch.
can anyone verify this?
thanks
