Hey,


I had the same problem with my 95 6.5 and it had a broken vacuum line from the vacuum pump to the wastgate solenoid on the drivers side valve cover. The plastic lines get brittle from the heat of the engine and age.

It was very easy to fix.

If you are getting vacuum up to the wastegate solenoid with no broken lines look at the vacuum line that goes from the solenoid to the turbo. Check for vacuum there. Unplug it and see if the rod move freely with your hand.

Report your findings.

Injector pump is very expensive compared to a simple vacuum hose. Start with the simple stuff first.

There are some people that will give bad advice on this forum. Be careful if it means buying something before checking to see what's bad.

I have never heard of this problem being an injector pump. It's the last thing I would consider buying. Right after I tried to see if it was low air in the spare tire.
