The engine is hesitating when accelerating, I have scanned the vehicle but there are no fault codes on the Engine. I have checked the spark plugs and the fuel injectors, fuel pump and they are in good condition.
Please could I get the engine performance wire diagram.
Thank you

Hello,

Most common causes for hesitation under acceleration/load is a high-tension issue.
This could be caused by arcing ignition coils or spark plugs.
It could also be caused by bad fuel, blocked fuel or air filter.

A good link regarding possible causes for hesitation:

Please see images below regarding the requested diagrams.
I had to cut the images and enlarge them for better display.

Cheers, Boris
