ok heres the deal this has been happening for a while, one of the main reasons why my car is still in the shop, my car when it is driving and you give it full throttle it starts to break in high rpm's mainly 5k and increasing, it starts to make the car feel like its struggling to get up there to 8 grand....we thought it was a fuel problem but i just had my RC 550c injectors and AEM FUEL RAIL put in today and still made no difference but now when in idel you give it throttle at 4 thousand it struggels for a litle bit and then lets go....now the shop its sitting at right now is telling me that it is because of my downpipe there is two parts on there that are about 5 in long both that have a little 2" piping mayb less then goes to a big 3"....could that be it or what is it, i just had enough of this ****** car, i jus got my fully built LS motor put in 2...and this is not goin good PLEASE HELP!!!

sounds like misifiring, what are your plugs gapped at?

TUR3Ovtec

i think there at 32

Check to make sure your plugs arent fouled, running extremely rich

Then gap em down to 28 and try again

wantboost

iTrader: (2)

try .30, that should help

TUR3Ovtec

that happened today the spark plugs were fouled all black on the bottom so replaced them with another set of NGK plugs, those were brand new plugs to tooken from my b16 from b4

TURBO HONDA

I had the same problem..i just gapped down....

TUR3Ovtec

what did you gap them down to because mines are at 32 right now

damn you have the same basic prob as me it sounds like.

TUR3Ovtec

yeah its becoming a real hassel and i jus want to get to the bottom of it so i can drive my damn car around, and nothing is seeming to work!

W O T

has everyone in this thread not told you to gap down your plugs?

98lude-t

i posted almost the same ? a couple days ago and only got a few replys.
I have tryed everything except the smashin down of the plugs or 2nd o2 sensor.
but will let everyone know when its fixed.

TUR3Ovtec

i just called the shop and he told me the new ones they put in today were already gapped at 28 but tommorow i can make sure when i go there...i jus need things that i could say hey check this and stuff like that....could it be the way things are set up????.

you called the shop at 1:30am? lol

98lude-t

does it do it in boost or just normal rev up slow outa boost.
if in boost that makes a diff.
but in regular vac maybe u have a spark delivery prob.

TUR3Ovtec

yeha because they just bought abigger space right next door and they are moving all of their **** out to the new place so there still there, and it does it when im in boost like when its gettin past 5psi's and then when ur in ideal it starts blogging up at like 4000rpm

98lude-t

yeah mine starts doing it about 6.5 just popping and spewing out blakc clouds of smoke.
Didnt think since i have a coil and ignition it would still do it {thats the reason i bought that ****}. but im going to go and gapper down and see whats up.

TUR3Ovtec

tell me wut happens...any1 else have any idea of why this **** is happening?????

98lude-t

are you running stock coil and ecu.

TUR3Ovtec

im running msd 8.5mm wires annnnnd a stock b16 ecu

98lude-t

a stock b16 ecu! whoa now yank them injectors out or you will burn up ur driver on that ecu

wantboost

iTrader: (2)

well, we just found out why your car wont run. are you really runnig inectors that big on a stock ecu!?!?!?!?!?!?! what are you using to adjust the fuel values?

TUR3Ovtec

wtf r u serious why???"?

98lude-t

that ecu is programed for the 240s or what ever they are not the big ones, it will try to open and close them off casueing the injector drivers to burn out. with out those no fuel=no run.

wantboost

a stock ecu cant control injectors that big, much less read boost. you need something to compensate for the larger injectors and the added air flow you are putting into the motor.
