Can anyone help me please. I have a y reg 1.8tddi focus. I ran it really low on dielsel and almost ran out. U did put £10 in and drove home fine. Latter it wouldnt start just turning over and not fireing up. I used the stuff you spray into air filter and it started. It juddered and spluttered a bit then went ok so I took it a few miles. Went home turned it if then same thing it wouldnt start so again I sprayed it Nd it started but if I wasnt revving it it would cut out. A friend had a look and disconnect a pipe he said was where the fule comes in. He told me to turn car over and see if anything came out. It didnt. So could this just be a clogged filters from running it so low. Any help would be very useful thanks in advance
