    Is it bad for the engine when you've been driving with a blown o2 sensor? All I notice is crappy mileage and a little less power.

    Carbon buildup and fouled plugs are a few things you'll see. I'd guess you could also clog your cats...

    Your truck isn't fueling itself properly. You should really fix this ASAP.

    Mine threw a code for o2 sensors every couple months. I would reset it and go on. Then in a couple months it would throw it again. Is this your experience or is it immediatly throwing it and not resetable?

    I drove with my intermitant bad sensors for over a year. Finally had the $ and got them from Dan.

    Eventually you'll carbon up the whole top end and still need to replace the O2 sensors :rolleyes: Replace them and use some Seafoam and Redline "Total Fuel System Cleaner" before you end up spending more money. Prolly gonna want new plugs as well -

    I'm planning on doing that in the next 2 weeks once I get the cash. Replace the plugs, air filter, o2 sensor, and use the fuel system cleaner. Just making sure but a blown o2 sensor can cause a rough idle with vibration in the cab right?

    You'll definately see rough idle. Vibration in the cab? From engine misfire maybe?
