Hey Guys,
Just a question I have been seeing some KR in 4th gear at WOT about 4k(Cars pulling 4-6 Degs of timing). I thought I got some bad gas so I went and got about 3 gallons of CAM2 gas( 100 Sunoco Race gas) drove the car about 20-30 mins let it mix and did a couple 4th gear pulls and no light
. About an hour later a got a P0420/P0430 cat below efficiency below threshold bank 1-2? I reset it, and this morning the car was back to puling timing in 4th WOT :/. thoughts, cat to exhaust gasket leak? Or do I have a sensor issue. I have had my exhaust set up for over a year and never seen a cat code.
