hi again finally got dealer from which i bought van{fiat ducato 2.0jtd}to take it back and have a look at it due to diesel entering the sump oil and causing rough running and runaway motor,he sent injectors off to be checked as suspected one of them was stuck open , one injector was faulty other three were ok ,so dodgy one was replaced ,got a phone call saying it was still missing a little bit but nothing like before and is quite drivable , picked it up and it is exactly the same as before ie down on power and missing/fluffing there is no real power when i put my foot down uphill or down , there was good power below and up to 3000 revs before im now having to push it to about 4000 and rev it hard to pull away in first, having to take hills in second gear, dosnt seem to be getting diesel in engine oil now ,engine is louder than before ie a bit of a rattle, seems to run better when first started up from cold but deteriates when hot egr valve has been removed cleaned and lubricated so i dont think its that ,some other exhaust or turbo fault possibly? wondering if i should take it back and demand a refund.
