I already spliced the harness for the 24lb'rs
I think it's janky to use narrow angle injectors in an oval port.
it's worth hunting in pull-a-part for a maf when they'll charge me like 5 bucks for it and it may help out in the short term before I can get it tuned.
First, the narrow pattern injectors, while not ideal on an oval port, are not the worst thing in the world. You simply get more port wall wetting. You will lose just a little power and fuel economy, but not the end of the world, and not something that someone like you would be even able to feel the difference.
Second, when will you get it through your thick skull that mixing and matching MAFS won't account for the injector change? A MAF is simply a sensor that puts out a voltage from 0-5V depending on how much air is flowing through it. the PCM has a map programmed in it, that tells it how much air is coming in at a given voltage from the MAFS. The PCM then looks at how large the injectors are supposed to be, combines that with a few other factors and decides how long to leave the injectors open for each cycle. Now, some
aftermarket MAFS have carefully tweaked the output to match the airflow % difference to a specified injector difference, ie, from a 19# to a 24#. Even when the
aftermarket companies do it, its a crapshoot, it often performs poorly, and even when it functions acceptably, it causes problems with the load calculations in the PCM. So, when even the guys using big, expensive flow benches to carefully calibrate thier MAFS to bandaid an injector change have significant issues more often than not, what makes you think that you can pick a MAFS at random from a junkyard and have it work better than leaving things the way they are until you can get it done right?
You are FAR FAR better off running a narrow spray pattern stock 19# injector (or use the stock 3.0L wide spray injector even) until you can afford to get a tune done, than to try to hack together some kludge of a mismatched injector, MAFS, and PCM combination.
