GT Diesel Power Problems
I am new so apologies that I may be going over some old ground.
On my 3rd Alfa 2 x 156 currently GT 2004 jtd (115000)
looked at EGR problems and have replaced mine albeit with a cheaper after market version - then ecu and throttle reset.
appears to surge every few seconds at constant speed not so much on acceleration which is a bit sluggish. Bit of black smoke on hard acceleration.
It runs better with the egr disconnected (engine light comes on but not for a few days) - still a bit sluggish but smoother.
Any help would be appreciated - thanks
