It won't shift into OD. And sputter's bad when the throttle is depressed

 

You are going to have to do a better job of:

1. Asking a question
2. Providing the basic info (engine, trans)
3. Giving a history of the problem.
4. Telling us what you have already done to try to solve it.

This is a great forum, but we have a definite shortage of mind readers.

 

Hey, we got the year (96) and the strong suggestion that it's an automatic since while technically 5th could be considered "overdrive" in a manual, 99% of folks would just say "5th gear". So that's already more than we sometimes get...


Jason,

After you provide the engine size (4 or 6 cyl) and confirm the transmission, we're going to really need you to describe the situation and conditions. "Sputtering" is a symptom of a wide array of possible problems. Also, could you elaborate about it not going into OD? Are you sure it's not shifting or is it possible it's directly due to the "sputtering" concern?

 

Very little information to go on. Most likely cause is a failed/failing upstream O2 sensor. Air Fuel mixture is likely not being managed correctly because of it. Not shifting into OD because you are depressing the pedal enough (due to lack of power) that the computer is keeping you in 3rd due to throttle position.

With more information, you'll get better advice. Good luck.

 

Ouch, that smarts! Nice one guys.
