Changed injector harness
checked main harness for chaffing. seems ok
Checked red ECU plug for oil nice and clean.
All filtres are changed every 5000 miles.
Can i try anything else or do i need to get a diagnostic done.

check coolant level temp sensor is in top hose with bleed plug ive had a few misfiring with low coolant in top hose ,but isnt there anybody near with hawkeye or such to help,alot of garages dont understand how to diagnose with test equipment
may take it to DLS i just wanted to try and sort it my self.
I did drain some coolant out to add anti freeze, but that was a few mths back, but will check
