Hi Welcome to the forum,

Afraid I can't help with your problem, but I would make a request that you attempt to refrain from using txt style abbreviations and attempt to include some punctuation and capital letters in the interest of making your post legible. This is an international forum, and we have many users for whom English is not thier first language. Also, people will be far more likely to help if they have not had to struggle to read your question in the first place.

Thanks

Mark

It could be a bad injector, not sure about Hawkeye but you can see something called cylinder balance on Testbook which shows you which cylinder is out of kilter. I've seen electrical failures and the odd broken injector spring and it has a similar effect to the harness (which would have been my first guess) but doesn't show up as a fault.
