Message According to the service records:
the Injectors are the upgraded 16600-15v02 and were replaced 10 years ago, which was only 1200 miles ago for the car.
I suppose they could be bad. Will test them.
--------------------------
Will use this data to do so:

https://conceptzperformance.com/wiki/index.php/Injector_Testing

*A good fuel injector will test between 10 and 14 ohms (O).If the reading is lower (not too common) or higher (very common), the injector is bad and must be replaced.

https://conceptzperformance.com/wiki/index.php/Coilpack

*should read 0.7O. Some have found their coilpacks to indicate as high as 1.2O and still function fine--as long as they're all consistent with one another it's likely that they're fully functional. Also keep in mind that there is some inherent resistance in the test leads on multimeters, and that resistance should be subtracted from the coilpack's reading to gain a true reading. For example, if touching your multimeter's leads

together yields 0.4O, and your coilpacks are showing 1.1O, this would mean they actually show 0.7O of resistance.
