Injector question
Hey all, happy holidays..
Here's what I got-
I have changed out my fuel injectors with a new set of
Accel 19 lbr's.. I had asked previously if any adjustment
was necessary after doing the replacement. The answer
was bascially that I didnt unless I wanted to delve into
the BLM? maps in the ECM. Thing is I think I am running
on the rich side. No black smoke or performance issues,
but I did find mismatched injectors when I pulled them,
one 25, one 24 and the rest 22's (per part number).
I can smell it is a hair on the rich side and it's annoying.
Cat is old and could be suspect- the only unknown here.
Keep in mind I have done the intake gasket, TB and runner
gaskets along with 02 and EGR valve and temp switch.
Tune up aslo plugs wires, cap and rotor. No check engine
light ever. TPS is set correctly as is the minimum idle adjudtment.
What the heck am I missing here?
Thanks

I gotta good deal on a set of 8.
I was told 19's wouldn't be an issue
and that they would be good for a
stock set up. So far, performance
and response are much better and
I haven't noticed anything odd since
the install. Idle is better but thats
about it.

I think you need 22 lb/h injectors like the stock.
If you want to stay with the 19 ones you should change your injector constant (in the chip) from 22 (stock) to 19 (the new ones).
If you stay with the old stock inj. constant the engine think it has bigger injectors so it act reducing the pulse width of the injector.
You should see (if you ave acces to a scantool) Higher BLM than 128 (around 140) if you go over 160 (the max allowed) you risk to go too lean.
