Engine/Transmission (1994 - 1998) wierd sound after shut down

[bradyw]

Sometimes after i shut my truck off it make this sound like an air tank bleeding off. Sounds like its comming from turbo side of engine only for a minute or less and it still is slugish at the top end. Other than that runs good. Just think it should have more power.

If you are running your your a/c then it is the system equalizing pressure

On top end problem it could be your governor kicking in to early. On my Mule I can get it to 2750 rpm (should go to 3000 rpm). But I'm usually running down the highway at 70. I have plenty of power to 2500 rpm but after that it starts to defuel.

Today i noticed that if i go up a hill empty truck only my pedal is dead enless i let up or pump it. It seems like if i dont feather it it flattens out. Im saving up for gauges sorry dont have boost or temp gauges. It feel like a gas engine that getting flooded and u let up on pedal and it takes off for a bit. Thankx

Check your linkage where it connects together. Ball and socket set up(I believe) mite need to spray it down or new parts for linkage.
