Failed HC emissions!

Nissan uses 3M injector cleaner now to clean up the injectors on the newer
cars. I know that Quest still uses the old saturated injectors till today-
and they are just diff impedance and flow from a SR20 JECS 259cc
injector.... they are all made by JECS. I was at Nissan today ( tranny
parts ) and my ex-cooworker friend was cleaning out the injectors on a
Quest. The stuff they use is diff from lets say the stuff U dump in the fuel
tank. What they use is pressurized injector cleaner. It basically hooks up
to the fuel rail directly, has a gauge on it to set up proper fuel pressure-
simulates fuel pump output. U cap off the return line to the tank and hook
up a air line to the injector cleaner device to bring up the fuel PSI- to
simulate the fuel pump to lets say 60psi and start the car up with the fuel
pump fuse out. The car run for like 20 min idleing till all the injector
cleaner solution has ran out from the injector cleaner setup... it will
start to sputter and die out eventually when all the solution has been
burned off. Then U reinstall the stock fuel lines to the fuel rail, put the
fuel pump fuse in and start the car up. Afterwards U change out the oil-
really have to cause this injector cleaner shit is hardcore and will
contaminate the oil. It cleans out the injectors, combustion chambers,
exhaust system, and the catalitic converter. Works really good and I have
had really good results from using it on Audis- really makes a huge diff on
them. I know Nissan charges like 60 bux for injector cleaner service at my
old shop where I used to work at here in Chicago-land area. I highly
recomend it over sending the injectors out to RC Engineering and having the
car down for a week or so.
