performance result from wrong injectors

[bitsoknittles]

all three were high; HC at 3.75 (allowable 1.60), CO 62.82 (allowable 15.00), and NOX 4.50 (allowable 2.50). I have a set of 13.8 ohms injectors; would it help to put them in the 88? I am thinking that the low impedence injectors are putting too much fuel into the motor causing it to run rich, thus increasing the idle speed (at 1k rpms, not 800) and the higher emission readings. If it is not the injectors, what should I be checking to get the idle correct and the vehicle to pass? I will be checking the EGR valve for cleaning/operation later today. Thank you again for your help! There was one diagnostic code for the knock sensor, but the knock sensor only turned on when the car was started and put under load (driving normally) initially. I turn off the car and restart it, the code does not show until another load, idling does not show the code.
