Weird noise on top injectors. Like a hissing sound only when hot .I put new injectors .No change It starts hard when hot .Im thinking fuel pressure regulator. It's not maf sensor ,or air filter.
Thanks

Well pressure test the fuel injector regulator then. But if you don't have such equipment a drive that also check for any type of leakage
