help~ reduced problem & nitrous prob.
my 2003 zo6vette has lot a problem.
i bought my vette in 2010. from america.
that time my vette is normal condition.
but, i tuned my vette. when my problem started.
header (obx-long) + x-pipe + custom end.
itg air-filter
os giken 2way l.s.d
msd coil + cable
&
zex wet nitrous. (<<<< now installing)
obx long header is not fit completely.
3# 4# o2 sensor was wrong direction.
i heard...diablo predator can delete 3# 4# sensors...
so, i eliminate my rear 02 sensors...
then, my vette spit a lot of pcm codes...
here is my dic.
p codes.
p0133
p0140
p0153
p0160
p1153
p0134
p0135
p0154
p0155
p0463
sometimes spit 4 codes...sometimes spit 8codes.
but, my predator was wrong version. it's only 2004 vette!!

so.. i ran my vette with trouble codes in 8months.
---------------------------------
a few weeks ago.
i hope install 'zex wet nitrous system'
so.. i bought all packages.
and, go my parking lot.
-----------------
here is problem!!!
reduced engine power + all guages down.



it was not my first time (reduced signal)
but, it was soon disappear... or when key off - started...it's gone.
but this time...it's not gone.
it always come to engine is cold.
it disappear..when engine is warm..or an impact on the road(rough road) ---i think-----
-------------------------------------------------------
here is second problem.
install 'zex nitro'
it activated on 'tps system + rpm system'
but, my tps sensor has not enough voltage.
it is not works.

tps wiring ----count top.
4. blue - >>is this tps voltage?
i think it's connect .
tps voltage ------ reduced engine power.
what can i do?
