53 2 Ford Duratorq rough running & smoke - LesCM19
In a London Taxi, same lump as early Galaxys & some Mondeos I think:
seems to have better acceleration with the turbo pressure hose unplugged off the EGR presumably so that the valve is always shut, but what would this do to invisible emmissions & the cat if its got one?
a colleague's cab went off the scale on the smoke test & was advised by a nearby taxi garage to stick a jetwash hose up the tailpipe & the ensuing startup would remove soot from silencer: smoke reading subsequently almost ZERO so is all the black smoke just soot not emissions nor EGR-design-fault-related smoke as he does not 'sabotage' his EGR?
Finally, anyone had one of those black boxes installed with a knob to alter timing, turbo etc and is it any good for power, smoothnes, not to mention smoke & economy?
