Focus1 6 tdci 2011 70k

Driving from cold engine rough running then about a mile down the road limp mode and error message service required. 

Connected scanner fault found dtc 1261 no 1 injector hi to low dead short.

Cleared dtc drove perfect. 

A few days later same thing happened .

Cleared again and checked harness and no1 injector connection it was clean and shiny so put back together  .

I have left the rubber covering off for now .

What's it for?

What to do next?

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.
