oxygen sensor

I have to ask, how long since a tune-up? 02 sensors are part of a tune-up. Are there any applicable trouble codes? Usually with any idle issues, I want to clean the throttle-body, check and clean anything that has to do with idle air system.

The generic basics for a rough idle is to check for a leak of some kind, fuel--egr--vacuum leak.

Auto zone did not have hook up the flash code was 44 that is where I got o2 sensor. Where is it at?

Hey Curt,

It sounds like you have a vacuum leak, and a weak fuel pump, or a plugged fuel filter.

Here are some guides to help you.

I thought I posted the 02 sensor was in the exhaust? Maybe I'm getting absent minded in my old age?
