Wondering how to ID the injectors on my car. They are not stock but they were installed before I purchased the car. I am just trying to find out what poundage they are. Is poundage a word?
Option 1, Take one out and see if there's any markings or part # on them.
Option 2. If you, or someone you know can read the PCM tune, the IFR table might be able to tell you.
(I say "might", because some tuners still like to butcher this table for AFR correction, and in that case it would only confuse you more).
Option 3, Send them to a shop that does injector cleaning and flowtesting.
