ive had problems for quite some time and I think I’m narrowing it down to an air leak but I might be completely wrong I’ll include to photos showing fuel trims one at idle and one at approximately 3000 rpm
if anyone could help and give me a clue as where to look I would much appreciate it
thank you .
But before digging too deeply, look at your fuel pressure. Looks okay In the first picture (idle), but in your second picture it's too low. I'd investigate further and take care of that first.
Thank you for your reply I have been looking into the fuel pressure for quite some time now I replaced the pump and after one week the fault appears again so I thought faulty pump so I replaced in with another from a different company lasted 4 weeks and then back to square one fuel filter has been replaced injectors replaced inlet manifold gaskets replaced , crank sensor replaced plus many more parts already done.
so I’m running out of things to look for ☹️
