2011 Ford ranger sputter
 

I have a 2011 Ford ranger that sputters under acceleration till around 30 to 40 at times other times it's doesn't clear up and is not throwing any codes any idea what it could be?

What do you have? 2.5,3.0,4.0? automatic,5 speed? What did you do prier to this happening? Details.....

It's a 2.3 i4 with a automatic transmission and the problem is just randomly happening. Happens when randomly driving, from cold start, and other times it's could run fine the whole day a never do it.

Check engine lite on? When was the last tune up?
