Hi, I had the injectors recently done and since then the car does not want to run properly. It is now under powered and when hot revs drop from 900 to 500 and then won't move or rev up. I out it into park and rev the engine a little and move it back to drive and although sluggish the car will then move and rev up. Please any help on what the problem is.

I have just checked the vehicle and I don't have a catalytic converter on the car. It was removed when the power pipe was installed.

Okay, lets check the turbo endplay. Remove either the intake or exhaust side to check the endplay of the turbo which will determine its wear. Here is a guide to help us see whats going on we should run the codes as well:

The turbo has a bit of play in it and is leaking oil. So needs to be seen too. But my turbo only kicks in at 1,800 revs and the problem is at take off once the turbo kicks in it runs okay.

The turbo works at all levels weather you feel the power or not. Can you please shoot a quick video with your phone so we can see what's going on with the endplay, that would be great. You can upload it here with your response. I can tell if the turbo is affecting the engine or not if I can see the endplay.
