ok i apologise if this problem has been discussed already i've spent several hours searching previous threads to no avail
Its a 2000 transporter 1.9 td indirect injection and in the last 18 months ive changed loads of parts and would be happy with it if the mpg wasn't as low as 25 and if you didn't ahave to press the throttle 3 seconds before pulling off just so that it would reach 2500 - 3000 rpm and not stall. Its so bad its actually dangereous at junctions
i've changed both front wheel bearings, timing belt and water pump inner and outer ball joints, new clutch and recondition rear calipers. i've also run several cans of injector cleaner through and there's no real smoke when accelerating.
so heres the symptoms from cold it takes about 5 seconds or more of turning over if i'm lucky but once its warm it starts perfectly ( yes the heater plugs might need replacing but i'm not going to do that until its running propperly) the most disturbing problem is the complete lack of power below 3000 rpm but once the turbo spools up you do actually feel a little power so that rules the turbo out and lack of black smoke when accelerating makes me think the injectors are ok i dont know about the injector pump timing though. its an ABL engine with 50kw about 67 bhp and no intercooler yet, i want to fix the main problem first, also its very slow to accelerate even when in nuetral.
tomorrow i'm going to bypass the fuel tank and filter and run it directly from a bottle to rule out a blockage in the fuel line and after that i'm going to split the exhaust when i find my home made tool for opening and putting back those lovely spring c clips holding the exhaust together but when thats done i'm left with it being a fuel injection problem injectors pump or timing.
Any other suggestions are more then welcome as i really dont know how to test if the injector pump is pumping hard enough or if the injectors are breaking at the correct pressure
Also does anyone know if its posssible to fit an lda from a car engine to increase fueling when under boost when i fit the intercooler?? and if so what engines are suitable i know where there is a damaged 1.6td golf injector pump that might do..

Any help would be great, sorry about being so long winded the more facts the less wrong answers
