When im driving down the road and hit about 2500 rpms the check engine light comes on. It's an automatic by the way. Could this be because of an oxygen sensor cause i have been told the truck has a bad one. Also, does a bad O2 sensor cause mpg to worsen?

oh, stupid me. I just remembered another reason why the light comes on. Could it be because the overdrive $#!+ the bed? I have pretty much no overdrive because one of the rings around it broke and i found it in the tranny pan.
A failed oxygen sensor most often doesn't cause a code to be thrown until some time after the owner has discovered it.
While a failed oxygen sensor will cause poor fuel economy, rough idle, and an annoying sucking sound (first through the intake, then through your wallet), it's not common for them to punk out at 2500RPM in the early part of the normal end of life failure. They tend to show more symptoms and idle, and to get happier with higher RPM.
A bad attitude and a Mega Viper.
Dash isn't cracked, steering doesn't wander, headlights are awesome, has good heat.
Sucking hard thru the intake very bad mpg a lil bucking. Cel comes on and and goes lol. My Durango did the same thing so that's why I'm leaning towards the 02 sensor. The truck has all new tune up parts
I have a 98 Dodge Ram 1500 5.9 the truck starts but idles at high rpm. The idle shoots down when I put it in drive it will take off when I give it gas but sputters and wants to die when I let off of it. When I get to 2nd gear it sputters on me. Could this be a bad o2 sensor?
welcome to df.
fill out your profile with year, engine, 2wd/4wd, auto/manual.
you should start your own thread and repost your question. otherwise, people will read the original question from 2 years ago and reanswer it instead of yours.
idle is controlled by a mysterious combination of the throttle position sensor (TPS) and idle air control (IAC). these terms are hard to search on this site because they don't meet the 5 character minimum word length for the stupid search engine.
so use google to search phrasing like this:
some problems are solved by cleaning the IAC pintle or well, but more are solved by replacing it. IAC is the primary control. but, sometimes the TPS can be bad, causing the IAC not to do its job.
