i'm korean. so i'm very poor english.

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?

 

Hopefully someone has the answer and helps you soon.
