hey i have an 89 camaro 5.0 tbi and it wastes gas like never before.i did the ecm check and i got code 44 lean exhaust what can that be?i cant afford my car waisting this much gas

 

Do not know all of the details on this one, but your O2 sensor may be the cause.

 

but then wouldnt it give me the error code for the o2 sensor?

 

As far as I know, unless I am wrong. 44 is Oxygen sensor lean and 45 is oxygen sensor rich.

 

in my manual its lean exhaust is that the same thing ?should i change it or not?will this make me waist gas or not?

 

I would imagine this being the same. What manual are you looking at? I use Chilton's and Haynes.

 

same

 

Im throwing a code 44 how to I fix it just replace it? It was supossedly replaced right when I got it because it would not pass smog and that was one of the reasons and they said they replaced the EGR and the o2 but maybe they didn't? She is wasting more gas now than she did before, so what do I do guys?!

 

Any update, Mia?

I just ran the codes on an 87 TPI. Came up with 13, 34, & 44.

I am replacing the O2 Sensor. I figured 13, and 44 would usually come together.

13 - Oxygen Sensor Signal Problem or Loss

44 - Oxygen Sensor Lean Error

34 has to do with the MAF Sensor. I am hoping the O2 Sensor might help fix this.
