Cylinder 3 fouling plugs
Hey guys! 2003 Evo 8, 135k. Engine is stock accept for exhaust.
Recently posted about having an issue running no boost. After investigating, found out my cat was plugged. So went catless downpipe.
Before having this problem, I had an issue where running WOT full boost, car would start to buck. Pulled my plugs, and cylinder 3 was fouled(may be related to cat being plugged). Since then I have had an issue with cylinder 3 fouling plugs. Here's a pic when I first pulled them, not sure how long these were on before I changed em
Before my cat was plugged and I was running full boost, it would foul every 3 weeks or so, but original plugs lasted months before the first incident. MTrying to figure out which route to go...what do you guys think?...I can't tell if it's oil, fuel or maybe electrical.
