First set of codes popped up last week, then cleared. Codes listed below.

p1085 - Major leak in the Purge system/hose in system not connected or filler cap
p0745 - Self adaptation of Mixcture formation for right bank of cylinders is at Liwith Value
p0946 - The efficiency of the left catalytic convert is insufficient
p0942 - The efficiency of the right catalytic converter is insufficient.
p2091 - Summen Error Der ...


Second set of codes popped up within 20 miles of clearing the above codes (pictured), then cleared. CEL light went on again after 10 miles.


Car runs and idles fine. No problems with WOT. I have 50k miles on the car, never any issues except having to replace 2 passenger O2 sensors. Modifications are ROW box, cat less headers with Xpipe. No changes/modifications on my car for 2-3 years and 25k miles EXCEPT a tune update (code popped up the same day I reinstalled my ECU).

Anyone know what I can fix or replace in regards to this purge system to see if this is in fact a mechanical issue?

Thanks

Any one?

Probably popped up because of the tune update. The update likely doesn't cancel out the catless headers.

That is at least where I would start.

simply brilliant . Problem wasnt present, installed tune.... now have problems. how could it be the tune? that doesnt make any sense

That's what I mentioned. Seems logical and I don't believe in coincidences ... but they felt differently.
