I posted to "Tech Help" originally & then thought I should post to the "Diesel Discussion" section - so now I have two posts on the same issue (newbie error)

I checked and the switchover valve has been bypassed. I plugged the vacuum line to the EGR & then turned the ALDA screw CCW
1 turn (virgin screw).

I had no smoking at all on idle....drove off & the car actually went fast! Stopped at market & decided to then drive at highway speed. Car then started having problems with power at high end.

Came home....cleaned banjo bolt (which was loose), blew air through tube....

Now I'm back to where I started with no low end power.....haven't tried yet at highway speeds....
