Injector question
I just had my injectors tested and cleaned. Five flowed at 15 and one at 20 pre-cleaning. Post cleaning, the five that flowed at 15 went up to 17 and the one at 20 stayed the same. My question is, is this going to cause a rich condition? Should I replace the one or does it really matter?

what company did you use?
these guys are top notch...

check out their injector cleaning process... "After the foam settles, the results can be seen, these flowed to within 1%. "

No. Mixture is controlled by ECU by monitioring engine sensors, most importantly the O2 sensor. Then it adjusts to achieve a 14.7 :1 mixture.
It does this by changing the time the injector is opened so the flow of the injector does not make a difference as the computer will correct for the flow change.

since the O2 sensor is not capable of responding fast enough to measure individual cylinder gasses and all 6 injectors are fired for the same duration, theoretically the one cylinder with the higher flow injector could run slightly rich while the others could be very slightly lean.
a ~15% difference in flow rate is not exactly a small amount- that one injector will inject approximately 15% more fuel for any given pulse duration than the other injectors.

I had a guy in my town clean them. He only charged me $15.00 apiece. With the two opposing views on it running rich or not, it seems like I would be better off picking one up at the junkyard and having it cleaned for 20-25 bucks.
