The two Holley 625 street demons (not typical Holleys) are starting to give me a little bit of a hard time... I've got to verify my O2 sensor is working correctly. I'm going to try and recalibrate it tomorrow. If that doesn't work it's getting sent back. I had my AF gauge start going crazy and I ordered a new O2 sensor but it was a cheap one from Amazon and I'm suspect of it as well... I've done just about everything to stop the hesitation with standing literally buying a wheelbarrow to pour...
Dual quads versus big hammer!!!...
