Feed it some carbs! That should pump it up. No such thing as a "lazy" O2. They just go bad over time and aren't as accurate. Do you have a CE light on?

Actually, talking with Venom over the phone, they contributed my lean condition to my O2 sensors being "lazy." It's generally at tip-in that the O2 sensor doesn't react fast enough to compensate for different air/fuel conditions. Anyway, I'm getting P0171 & P0174 codes as I've got the factory upstream O2's in place right now. They only come up about once a week. Hoping the new Denzo's I ordered yesterday clears that up.

I've always heard it as a slow O2. Just depends where your kid goes to special ed I guess.

I did have a p0171 cel. Bank one lean. I reset the computer and the cel has not come back. It's been 4 months. I am going to replace the downstream sensor and take if from there. I have read the how to article and I am unable to match the part number with the correct sensor. See the web link below. https://www.autopartsway.ca/secure/cart.cfmI hope this is the right sensor Thank you for you help
