I own a 1994 lexus ls400 the problem with it is extreme rough idling when first started but when the car warms up it idles great but has a lil miss i'm told that the miss is my #3 injector also when i accelerate gently the car drives normal but when i accelerate with force the car sputters but goes from a dead stop pretty fast but is trying to catch up PLS HELP

If someone has already told you that the #3 injector has a problem, then what can we possibly tell you here that would be any more certain? That the engine is rough when cold would be like ... obvious? That it would smooth out "but has a lil miss" would be like ... obvious? That it accelerates Ok under light load, but sputters under full load, like ... you know, obvious?

Perhaps you could investigate that #3 injector diagnosis, resolve that potential problem, and get back to us once it is established that #3 injector is not contributing to the above symptoms.

how exactly does an injector "miss"?

a "miss" refers to a misfire, so either the iinjector's getting stuck open or closed, or the spark plug isn't firing properly.

perhaps you were told that Cylinder #3 was missing.

a cold miss is often due to a dead or dying ignition coil/igniter or rarely a dead ECT.
