What could be the issue?
Hey there i just had a new engine dropped in my 16 sti i was out running some logs for the tuner and noticed when i shifted to neutral from 4th instead of it saying its in neutral it says its in 6th did it once or twice. This is a brand new clutch i cant really test if its slipping or not because the tuner said no WOT pulls yet but it felt fine. I scanned it with a cheap scanner i had at home and all that came up was maf codes because im running full speed density and the maf sensor is unplugged but i do have a snapon scanner im going to take home from work today and see if thats any better. Ive read that it MIGHT be a neutral position sensor but it seems unlikely any thoughts?
(If you look at the end when i shifted from 4-3 i didn’t let off the clutch and just pulled it out of gear straight to neutral then let off the clutch thats when it said i was in 6th)
