Smokey 940
Hi everyone,
This is my first post on here, I own a 1995 940 D24TIC. What a car, I love it. Currently at 182,000. It's been pretty smokey since I got it, its possible that a previous owner has messed with the smoke screw on the pump.
I get a decent cloud at start up when cold which I think is pretty normal for these engines but also leaving big clouds when pulling away from junctions etc. When on boost there's barely any smoke but off boost and accelerating it can be quite embarrassing. This did actually get worse when the fuel filter was changed. Is it possible that now I've got a clean fuel filter the engine is over fuelling until the boost kicks in? I'm hoping it's just a case of backing the smoke screw out a turn or so but with this being my first D24 I'm hesitant to start messing with the pump. Any suggestions or help would be greatly appreciated.
