Need HELP!


Looks like the short term fuel trim is almost maxed out in the negative. That would imply the egnine is getting fuel from somewhere other than the regular injector function or that air is heavily restricted.
Maybe a faulty or too large of an injector? They they said they were OEM, Denso not Motorcraft. Or not getting enough air to it. I've done a smoke test as well and can't find any leaks.
