Thread: Help Bluebird Problems..

ok bluebird motor
stock turbo-t25
ser ecu jim wolf tuned
370 cc injectors
(i cant seem to find the plug for my o2 sensor
so its unplugged)


ight well i thought i had an fuelrail/injector problem so i got another set of both put them on and its starts up right away but when the rpms drop back down its like it wants to die so i took it for a drive and its still bogging, i have to crank the fuel to like 60psi for the bogging to go away, and when im comming to a stop its like it wants to die, it did twice... im not sure *** exactly it could be i have no power in first gear and the rest seem sluggish also, when i change to fresh spark plugs.. it runs pretty fine rich as hell considering fuel is up 60 psi...
also is there a difference with the purple top injectors and the ones that come grey??

i gapped my injectors to .28 and checked my intercooler piping for anything that was loose and tighted wat i could. IT drove a lil better but still bogging and when i get into it it boggs then picks up but when i let my foot off the gas it dies... i wanna know how can i do a boost leak check.. also my fuel psi keeps bouncing not too sure why...any help is valuable thanks

fuel pump? fuel pump fuse? check to make sure u have ur hoses (under the hood) right for fuel. make sure u have the vacuum hose from the manifold to the fpr. and leak free

btw, i'm having the same problem. check your TPS as well while ur at it. check the voltage : 0.35-0.5V closed and 4V open.
Im having problems with my tps which is causing it to have the same symptoms but mine doesnt die as much. it bogs and feels like it will die. and it struggles from 2-3k, after that it's smooth.

only difference is, im using the BB ecu, and BB o2 sensor. you definitely want to plug in the o2 sensor. mine wouldn't start without it.

check your IACV valve... But for sure find the plug for the O2 sensor that is some important stuff maybe check your timing while you are at it...

timing is set at 15 as for the o2 man ive searched through and out for it and cant find it anywhere , one guy i spoke to said he hasnt had an o2 for 1 whole year now, lol but ima take some more vids and pics and post them once i check these things you guys are talkin about....thanks

anybody else have any imput???

Search "pressure tester". You may want to make ur own pressure tester to find leaks. Have you done a tune up?

by the way.
where did you get your pillar gauge pod from? i've been looking for one for a b14 but there doesnt appear to be one made for it.

oh it came wit the car when i bought it where have you been looking... im sure i can find one for you im on a couple other forums so ill kepp an eye out.. . ima check the tps right now..

i also re grounded my maf umm my vac gauge stays at 19
and the bogging prob is only in low gears but once it gets goin it seems smooth

You should find your IACV valve and give the screw on top a turn and see if that works the problem you are having the same problems my buddies sr powered 240sx was having until i adjusted the IACV valve and bamm it idles and doesn't buck or any other problems...
The screw is on the passenger side of the car right next to the power steering pump....

sounds good. thanks bro.

I'm having the same problem and it smoothens out after 2.5 K RPMS. I have recently tested my TPS and im getting 0.02V closed and about 0.9V to 1.something V WOT. Which is weird. and i Know im measuring it right. I have even tried hooking up another TPS from my auto GA16, and turning the sensor by hand. The same readings. so im sure my sr20 sensor is fine. I have also cleaned the connector and tried another ECU, so it must be a problem with my Wiring. So definitely check your TPS. I get about -16 to -14 PSI at idle.

IS THERE A write up on how to check the tps?

HAVE YOU Tried searching?^
