so i know i already asked about injectors once and i
got some helpful advice but i got to thinking is
that going to make me run really rich and fail
emmisions i live in texas and nox is high to begin
with... also if it did run rich would a throttle
body from say fastman compensate???

Instead of compensating with more air, try a better ignition system. I have an accell 300+ digital system (its plug and play, easy to install) or you coud go with an MSD of Crane system, any one will do the same thing. Hot coil+ mutliple sparks= really clean emissions. I'm up in Ontario Canada, and we have California specs for our emissions, Mine are so low I've never had a problem in 10 years

High nox readings on a 94 could also be from a bad
or malfunctioning EGR valve or it's electronic
solenoid/switch.
You also need a cat on that motor & not gutted, Also
make sure there are no exhaust leaks before the cat.

your absolutely right about that every great once in
a while it pops a code for the egr system but then
its off for months at a time.. have a cat not gutted
and no holes but this has been a problem since
before i modded it could it still be the egr?

Other symptoms a bad/faulty EGR can cause,
Poor idle, Poor gas mileage, Engine pinging.
Make note, The reason I mentioned you need a cat and
no exhaust leaks, The EGR will not work properly on
those motors otherwise.

If you were to pull the codes you would find the
code for the EGR is still there, Stored/saved.
There has been problems with 3in. on the 3.9's
Check for the stored codes, If the EGR still shows
up, Get a new one. If the trouble shows up again
you can try capping your 3in. pipe with
a short 3 - 2 1/2in adapter.
Glad to offer what help I can.

ok have been thinking about it lately anyways just
no time to do it at the moment. and after the new
one is installed would the 3 in cause the new egr to
fail prematurely

No, Install the new one, clear codes by leaving neg.
off battery.
If the code reappears then try capping the exhaust
pipe like i said.
I'll check back from time to time see how it goes,
Give me an update.

Won't be as bad as you thought, Two bolts and 1
electric plug. It's easy to get to.
Be sure to clean the EGR port and surface before
install (most likely heavy carbon)
and use a new gasket. (should be included)
