the ECU can suspend the 420 monitor if it thinks the front sensor is bad, seen this many times... kinda smart for a suzuki.
if you look at monitor status, you may see is pending all the time, (frozen) <--- true, that code is stuck there, not moving
old a new sensor is slow. <--- sorry, not sure what you mean
got air leaks in front of cat? or the infamous exhaust header #4 down tube cracked? <--- tube #4 weld is still holding for now, I think there may be a whissing sound coming from the donut gasket area where collector and the downpipe connect, but with all the engine noise is very hard to point out, I will try a rag on tail pipe to increase back pressure and look for leaks on the whole exhaust system
non of this is serious yet. (running wise )
A leak in the exhaust system could also explain why my LTFT is a little higher right?
