Re: 5kt injectors leaking, or what??
Had a similiar problem once in an 84 5000 I had. It turned out that the
o-rings that seal the injectors to the head harden over time and allow air
to seap by preventing a quick start. After you crank the engine for a while
the seals get pulled against the head and engine starts but not before
dumping a lot of fuel in. This happened to me only after the car sat for
ten minutes or so, if started right away it was fine. Worth grabbing your
injectors and feeling if they feel loose in the head.
