Thank you much guys... I just bought my Benz and we're still getting to know each other... So those lines should be dry then... Ok. They are dry then... :0 I consider sluggish acceleration when I compare it to my '87 Cadillac Fleetwood brougham and makes it flle like a bugatti veyron in comparison. I Know Diesels are slow but not this slow... I changed the first fuel filter and I just discovered an oil filter-like fuel filter which i'll proceed to change and see what that does. Turbo's doing good as far as I can tell, once it kicks in the car flies. Valves... Hmm... I hope I won't have to go there. Again, thank you all, really appreciate the ideas!
