Hope someone can help me out there as this problems is really bugging me now
Got a 52 plate transit 2.4 duratorq, 71,000 miles. Starts ok, runs fine albeit low on power (no response from lower half of throttle pedal, as though in limp mode), no MIL light of glow plug light showing other than when you first turn ignition on, have had codes read & showing P1664 & P1564 (in that order).
So far have cleaned EGR valve, replaced fuel filter & air filter (filthy) CAT previously removed,cracked injectors & fueling there seems ok, cant see any obvious splits/airleaks on pipes. Can anyone give me any ideas.
Thnaks in advance
