Hi all,
At last I have changed both the fuel filter and injectors.
After depressurising the fuel system by disconnecting the fuel pump the First Job was the fuel filter, which snapped inside the connector & I presume points to cheap plastic being used. I depressed the tabs on each side and it moved a little but then decided to break, not a major problem as it was easy to remove the broken piece but annoying all the same. The fuel filter strap needed to be pried off and then tapped back into place with either a hammer or the blunt end of a screw driver on reassembly. The fuel that came out of the filter was black in colour. New filter fitted and job complete.
Now onto the Injectors,
Following the Haynes book of dirty hands in photos and how too advice step by step I got to the step where I had to remove the two bolts holding the fuel rail to the head. Using a T30 socket I managed to 'Break" loose the first bolt but when it came to the second it proved more of a challenge. Whoever it was that fitted these bolts originally used thread lock and on this one it just would not budge so much so that it rounded of the innards. With this problem I had to use a cold chisel to tap away at the bolt until it decided to budge.
To loosen the bolt behind the rail I used a 10" extension with a 10mm socket.
This just left releasing the fuel rail loom and wiggling the fuel rail and injectors out off the head.
I replaced all 4 injectors as a matter of course, at 22 quid a pop you have nothing to lose and have piece of mind knowing you have new ones.
With everything reassembled I cleared the fault codes, re-pressurised the system, checked for leaks and took the old girl for a spin and I can say that no MIL came on well not on this trip anyway, I can hear the injectors working and the car drives much better with better acceleration. Tomorrow I will take it for a good long drive to see if the problem has been fixed.
