I got a set that test at 16.2 on all 6 that are out of a 2.8 set up. a set out of a 3.1 that all test at 12.3 and a set off a 3.4 engine that reads 12.3 on all 6.the opening in the end of the 3.4 ijectors is bigger than the 2.8 or 3.1.I have no idea what brands they are or any of that.I just know they where all working ing there respective cars

 

The first set is the only one that is flowing as much as it should be, use the 2.8 ones that are flowing 16.2, the others are not flowing as much as they should be, from what I recall stock was 16 or 17 for 2.8 injectors, and obviously a 3.1 and 3.4 should be higher, I think 19 lbs for 3.4l.

 

Wrong.

He's talking resistance measurements. Anything above 11.8 ohms is acceptable, anything less automatically goes in the round file.

Again, as I've posted numerous times before:

2.8 injectors and 3.1 injectors: 15.4 lb/hr flow rate. May also be 14.7 depending on which injectors are installed.
3.4 injectors: 18.4 lbs/hr flow rate. Same as the 3100 (small port).

DO NOT use the 3.4 injectors on a 2.8. I made that mistake and only got rid of the code 45 (rich exhaust) by swapping to a full set of 84888s.
