Hi Emma I hope you are well .im sorry to hear your focus isn't running well and I totally understand how frustrating this can be. can I ask how far you have driven since replacement?

Customer: replied 6 days ago.
less than 1 mile
Customer: replied 6 days ago.
the mechanic did advise me to drive for a while, perhaps on a motorway however the mile i did drive i couldnt get past 20 miles per hour
Expert:  Kevin replied 6 days ago.

ok so this is not normal, sometimes you can get a short period of driving where it can be rough as the injector is relearned but it should still drive

Customer: replied 6 days ago.
Ok do you think i should drive it a little longer for "relearning" and if so how what duration/distance should it take for it to work normally please?
Expert:  Kevin replied 6 days ago.

it won't get better this is not normal and there is an issue with the injector or something that's been carried out

Customer: replied 6 days ago.
ok thanks, ***** ***** take it back to the same mechanic then? he said if it doesnt work then its an electrical fault - is he right or having me on?
Expert:  Kevin replied 6 days ago.

it's difficult to know I would certainly give him the opportunity to put it right because he's made it worse would make me believe there is an issue with the injector he's fitted
