Saw a few posts on this issue but mostly for the 4.0. I have the 2.5l with the 5 speed and am having issues getting it to pass smog.
Here is my first test, everything was good but the NO. It was NO = 682 @ 15MPH and 1082 @ 25MPH. Guy told me my CAT was on the banned list but that I was grandfathered in so that was okay. However, after talking with several shops, the idea was that the CAT was actually bad. So I put in a new CAT. Magnaflow EO#D-193-105 (339005).
Took it back in for another test after putting about 60 miles on the new CAT. I also drove about 30 miles before taking it in just to make sure it was nice and hot. Results or the 2nd Test were NO = 32 @15MPH and 850 @ 25MPH. Limit @ 25MPH was 623. So I FAIL again.
I have no EGR. Don't see any leaks in the exhaust. No idea about thermostat or the O2 sensor. Never did any Sea Foam as I don't really know what or how that works.
Can anyone provide any ideas or help?
Thanks
