I've got a sputtering issue guys. Not sure what's going on. It just started it. Does it under heavy acceleration. It's got 157,000 miles. Pmd relocated. But not sure how long ago as it was already done when I bought it. Had it over a month. It doesn't smoke while sputtering. Also when I bought the truck I had really good oil psi. Around 80. Now it runs around 40-50. Not leaking or losing oil. Any suggestions?!?! Thanks guys

 

If it has the original injectors then they are probably shot.

 

Do you have a boost gauge? If so, what is your boost when sputtering? I believe it to be fuel related, but overboost and defueling could be the cause, but i'm not too familiar with that.
