Help needed Loss of Power

Hi, i am a new Voyager owner.
 
I was wondering if anybody has had a problem with  lack of Power! My Voyager was in the workshop and changed Glowplugs. Before the car was in the workshop the car was fine, after picking the car up i felt a loss of power ( at 3500 rpm )! That i am not a mechanic my knowledge is limited! I have asked a few friends what the problem could be! But nobody can!
I hope somebody can help!!!
 
Thanks taffyd

Another thing  what kinda van  3.8?? 3.3 what year  stuff like that is good to know inorder to find a problem because no on is there but u to see the van.

Hello Chrysler Tech!!
Thanks for your quick reply! My Chrysler is a 2.5 Turbo Diesel, Model 1996. Just to explain at the moment i am living in Norway and the workshop is playing dum (do not understand english ha ha)! I put the car in to change the glow plugs after picking up the van i did a test drive and there was no power at all! The mechanic then checked the engine and found a few pipes were lose, i think they were going to the Turbo, but i could not see properly! Did another testdrive, drove better but it doesnt feel as if the Turbo is kicking in. I hope this will help you, because i need solid info so i can go back to the workshop! I dont use more fuel then before and there is no sounds coming from the Turbo! Any suggestions would be helpful

why would u replace your glow plugs ne way????  what ever they tok or or did not hook back up then thats the prob. Most of the time loos of power on a turbo  is the air flow into the turbo  loose hose  or waste gate vac  things like that  or a sensor is unpluged.
