Not sure if this is the right section. But I am looking for assistance with my 2002 F250 diesel it has the 7.3 L and about 142000 miles on it. Anyways the other day the turbo started to act up. When you try to accelerate quickly it boosts for a second then seems to dump the boost and all turbo power is lost. If you seem to ease into the throttle then it doesnt seem to dump the boost. This is my first diesel and am pretty mechanically inclined so I was looking for places to start checking. I had one guy tell me it sounds like my wastegate spring is bad and that it is not holding enough pressure. I will look into the wastegate thing this weekend but was also looking for other suggestions or similar issues you may have run into. Thanks for your help in advance.
