sputtering lumina

[meuhus]

hello all

i have two dead cylinders for sure (maybe more)

i pulled the front plugs
#2 and#4 smelled like gas #6 is normal

i have spark to the dead cylinders
so i dont think its a spark issue

would a fuel injector (or two) be stuck open?
or is it a valve(or two)stuck open

pulled plug wires started it up had spark at the dead cylinders
(witch i know you shouldn't do but i dont have a spark tester)

the two injectors that i can get to are working(#1 and #6)
but i can't get to the rest because the plenum
(upper manifold) is in the way
should i take it off and check the resitance in the injector?
what should the resitance be?
the wiring diagram i have shows all the injectors tied together.
so when one is on they all are on?
my hayes manuall doesn't got into detail about this one.
says take it to dealer

i can not afford that i don't know who can but it must be nice.

exhaust kind of smells rich of unburnt gas
but it doesn't smoke

wires look good to sensors

i reset computer codes are gone

changed tps nothing happened

i have also changed the following sensors in the past

crank sensor
tps
iac
and
two coils

i replaced the new tps with the old one to see if that changed any thing
but it didin't

i think there could be two valves stuck open
or the fuel injector problem
could it be a bad fuel pressure regulator?
to much pressure?

have plenty of fuel to the rail
don't know pressure
but it squirts out of the shader valve in the rail pretty good

don't know where else to look
