injector light flickers on

hi
firstly, thanks for all the help and replies to my last thread - I have had a new starter motor fitted which helped for a couple of days - but it wasn't the answer so today I have had new leak off pipes fitted and fingers crossed - hope this sorts the problem. However, now I have another as on driving it home from the garage the fuel injector light flickered on and off about 3 times but there did not seem to be any loss of power as it was when i was going up gears - has anyone any ideas? I am hoping that someone will confirm it is a bit of dirt in the injectors from when the pipes were changed :scratching_chin:

Stick it on diagnostics get the faults read could be a number of things.

The connector to injector number 4 needle lift sensor has been disturbed would be my guess.
