Does anyone know what the ontime at idle for a stock 19lb injector on a pretty stock 92 5.0L should be? Any help would be GREATLY appreciated!

At idle, (hot) the pulsewidth should be around 4.6-4.8 ms

No I meant is he using the tweecer and thats why he needs the pulse widths to compare to his now modified ones.

Thank you kindly sir!
Nope no tweecer yet but hopefully one day. I've been trying to figure out why I'm getting fairly lousy mileage. Back probed my injectors pulsewidth at idle was 5 ms, seemed a bit high to me but I guess its not too far off spec, my idle is set a bit high right now anyway(900rpm). Mass Air, O2's, ECT, all are operating correctly, think I'll start looking elsewhere like maybe a draging caliper or something.

Have you tried pulling codes?
Sounds like it's limp home mode where it just dumps fuel into the equation thus making it wast far more gasoline.
Have you eliminated the smog equipment? that would set it in limp home mode.
Get the tweecer and cancell all that crap out.
You'll be happy you got one.
Plus it doesn't need to be an rt.
