Leaking Down Fuel...But Injectors Test Perfect??
Ok,
For awhile now, my car has been half-way hard to start once it has sat for a while after being warmed up... Sitting overnight is no problem....When it finally starts up it runs rough for a little bit and sometimes put out a little bit of black smoke, but not much..
I had the dealership run a diagnostics test..(Ohm the injectors and whatnot)... And they told me ALL the injectors were working the way they should....They all ohmed out correctly.
I pulled the vacuum hose off the fuel pressure regulator and had a buddy prime the car... No gas in the line.. No problems here..
I don't know what to do...Unless one of my injectors has a bad O-Ring or something, I cant find any reason why there is fuel in my engine.
Can injectors be leaking down and still Ohm out good??

"Ohming" an injector is a test of limited usefulness at best. It doesn't tell you a thing about whether the injector leaks or is plugged or not, it only tests whether the resistance of the coil is within specs.
