I wonder if anyone has ran into this issue…..I’m on my second O2 sensor from Holley and I’m having it stuck on 35.6. The car runs fine which makes me pretty certain it’s a false reading……the second sensor ran good and gave me good AF readings for about 100 miles and now it’s stuck there again……when I take it out it’s pretty black and covered in carbon…..I just ordered yet another sensor and this time I’m gonna run a Innovate Motorsports 3729 Heat-Sink Bung Extender HBX-1. Are you guys familiar with this….will it fix the issue? Thanks for you input!
