Hey fam,
Haven't posted in a while, the Max has held up well. Quite frankly, after 6 years I'm not sure if anyone I used to post with is still here. Anywhooooo
The Max starts rough warm, idles rough when in park. I have previously had P0420 (catalyst efficiency below threshold), but these codes have been popping up for four years and I generally just clear them to never see another one for months.
Is this a sign the headers are gone? I also noticed some liquid near my EVAP, could the rough idle and start be a sign of a leak somewhere.
Accel and power seem just fine, fuel efficiency is still 23.1 like normal.
Any ideas??
Thanks

Follow up: ended up getting a code P1420 ERG System. I suspect the Cats are failing and will order a Racingline HFPC. When I put on the new Cats I will clean the ERG system and hopefully fix the whole problem!
