I have a 03 focus 1.8TDDI, 150,000miles on the clock. Had been working well up to last year where I had to put a new fuel injector pump in it. Then 3 months later I noticed that it was lacking power took ages to get up to 60/70mph but it would make it eventually and could even do more.
Last week it started making a funny noise too, it hasnt stopped starting and will still drive with the same lack off power. it is now making this rasping/rattling noise. I have a video of it but didnt know how to upload to here.

ANy advice would be helpful as my hubby works long hours and wont get the time to look at it for another few weeks. I have a toddler and dont want to risk driving it down to local garage.

Thanks
