Ian Lockley Posted September 15, 2021 Author Share Posted September 15, 2021 This went on to become a breakdown and recovery. No 1 injector failed with a dead short across a the hi and low solenoids . RAC also diagnosed p1261 injector fault . If it had been p 1264 it would have been no 4 injector. I purchased a s/h injector of the correct code numbers printed on top of failed injector . Cost £110 delivered DHL this morning. Had the tip soaking in brake cleaner for a few hours with the rest of injector resting against a box. Cover pipe out let's to keep dust out . I CLEANED AND ANNEALED THE COPPER WASHER THEN RE USED IT. Fitted this afternoon all went well . DO NOT RE PROGRAM. started a little rough but soon expelled the bit of trapped air . Smoothed to a good tick over . Still had engine fault on dash but not in limp mode Connected scanner cleared DTC P 1261 . ADDED " CLEAN DRIVE" FUEL INJECTION CLEANER TO 1/4 TANK OF FUEL . COST £20 DROVE 45 MILES CAN TELL DIFFERENCE ALREADY . MORE RESPONSIVE. WILL COMMENT MORE WHEN I HAVE USED THE REST OF THE 1/4 TANK . IT SAYS TO DRIVE TILL LOW FUEL WARNING COMES ON THEN RE FUEL.
