I should have 22 but I don’t know how to tell. About a year ago I sent them to Jon for rebuild. Got them back but there was no paperwork with them, and it didn’t make any difference in idle. I don’t know if there should have been paperwork or not. Before I do anything else, I need to find out what flow rate these are and go from there

22 with more fuel pressure should make a 24 but something I read says that is better to be small since you can control the pulse width better when it is a smaller injector. The bigger ones at small pulse width are harder to control. IIRC.

I mean, you gave me a shirt and asked me to clean it. I'm not responsible if the shirt doesn't fit you because it was too small to begin with.

I think the problem is that you sent him a set, he sees what the flow should be BASED ON THE INJECTOR and he goes with that when he checks flow rate. I suggest you bring him the number and ask him what the flow rate is FOR THAT INJECTOR. Next question is what your 89 Flow Rate should be. See what he has to say. He did the work. I can't imagine he would lie to you especially when he isn't at fault.

Not blaming Jon for anything. He didn’t sell me injectors in first place, and only rebuilt injectors I sent him. To be clear Jon has nothing to do with my concerns, if anything he might be able to help me

I agree. He has no reason to lie in your case plus I have verified his work a time or two so you are safe

If it turns out that 19 lb injectors were installed in my 89 and I make sure the ecu is set to 19, what will be the effect on my engine until I can rustle up some cash for 22 injectors Is there a number on the injectors themselves that I could look up to see what they are?

He seems decent so go ask. It's like a girl. 99 out of 100 will slap you when you say "wanna fawk" but you live for that 1 in a hundred that will say "YES".

My Bosch 3 are either 19 or 22 depending on the fuel pressure you are running. They are 19 in Ford because of the lower fuel pressure. He suggested turning lowering my fuel flow rate in ecu to around 19 or a little higher to see if effects idle, although he said injectors don’t normally effect idle, but my fuel pressure might be a little on the low side, which I have always thought was true.
The color of the correct injectors could be yellow or orange because manufacturers color has changed slightly over the years
I will use my ostrich to lower rate, but I have feeling it won’t matter at idle. Jon said his experience with l98 engine is that some idle smooth and some idle like crap

Didn't know he got around to tuning. Good to know, just in case.

I was able to get number of injector today. It is 155700. Jon told me they are 19 lb at ford pressure of 32.5 but 22 at 43.5. The problem is when you look up that number on Webb it list it at 19 at 3 bar. FIC told me the data on Webb is wrong

I think that threshold defaults in the 575-600 range for the lower air flow (g/sec) range. Try raising the bottom cell (or two...depending on your idle air flow) into the lower/middle 600s. You may also need to raise the lowest MAF table values a bit....especially if you have the problem when cold (open loop).

That's because he didn't tell you what I already said to do...in post #15. That post provides all that Jon told you today + how to change swingpoint on O2 sensor so it will run richer (better) at idle.
