ey fellow sau's

recently iv been having quiet a few problems with my car,

first started with the ecu, it was running on 4 cylinders, changed it to another one and it ran fine,

next the car started backfiring heaps and i mean heaps, even if you just press the accelerator a bit it will backfire

and it seemed to be running really rich, you could smell fuel out of the exhaust

then the car wouldnt start at all until i gave it a bit of gas, and it would finally turn over, it still ran like shit,

checked the coil packs, and when i took out number 1 there was no change in engine noise, so it seemed like it was running on 5 cylinders

replaced the coil pack with another one and it still the same shit, changed the spark plug on that coil pack with another and same shyt,

whilst plugging and unplugging coil packs, the car turned off

and now it wont crank over, i think its hydrolocked

im asking what is the right way to un hydrolock the car, iv read about it briefly but don't wana stuff anything up

could it all be related, i.e a leaking injector causes the car to run rich and backfire and then hydrolock it?

any help appreciated thanks,

mods as per sig

remove the spark plugs and hold a ciggy lighter to the hole*

i find inserting lit party sparklers into the plug holes works best :P

is this still gona crank the engine? so that the fuel comes out? i know i have to use a clean rag or towel to get the fuel out,

thanks for the quick replies fellows

Just remove the plugs and coil and the CAS plug no need to injectors.

The engine will crank nice and fast... well should and speed in which would atomize any fuel and come out with the air being compressed out the spark plug hole.

Best do an oil change too once its up and running, fuel has probably seeped past the rings and into the sump, diluting the oil. And i would be pointing the finger at a leaking injector for the cause.

cool thanks people,

so would a leaking injector also make the car run really rich and backfire, id rather diagnose more problems tomorrow than fix the injectors and find out something else is wrong,

il just have to wait and see tomorrow

Yeah if the injector is shagged it might not be shutting off when it should, thus letting fuel seep into the cylinder. If your getting one fixed you may aswell do them all.

is that a serious answer or another smart ass comment

aww c'mon...lighten up...it was an attempt at humour...albeit a poor one.

I was only trying to help out mate.

Best of luck fixing it...or finding out whats wrong.

hey ppl,

just letting you know that i fixed the problem today, Cylinder one had a shit load of fuel in it, had to crank it twice to get it all out, it was like a puddle, no joke

on injector 1 the o-ring had come off causing it to leak,

the back firing has gone and car runs good, just waiting for some splitfires and more boost now

thanks to everyone that posted

lol and Dirtgarage i know u were only joking around, kinda funny now looking back when my car is all fixed, but yesterday wasn't my day

i think its time i become a Vic Member to pay back for everything this forum has taught me,

cheers

      Have you done the Ignition Sync Wizard in the AEM software?

      Find out what RPM it was idling at with the IACV unplugged. It's very weird that the rpm didn't change at all, and then it stalled. When it stalls is it nearly like a switch off, like you've turned the engine off? Or is it more stutters and sputters and coughs to death over a few seconds? Or does the RPM just slowly keep going down and down? Have you done a test of trying to start it with the AFM unplugged? Does it still die?     If you Follow Josh's advice on using Nistune to check the voltages (which is a perfect method!) if you see anything out of wack voltage wise, THEN get the multimeter out and read the voltage directly at the sensor. If the two vary, then you're now looking for a wiring issue vs a sensor issue. So be aware, what the ECU sees, may not be what the sensor is actually saying too...

      RB25DE NEO with Haltech ECU

      You very likely need to get it on a dyno and tune it. My assumption is, you've got an RB25DET tune in it, which has a different manifold, different injectors, and different cams as a minimum. What O2 sensor are you running?   When you say it runs extremely rich from idle all the way to redline, is this just free revving it you see that?

      I seem to the be only person that is using a Haltech 2500 on an NA motor, I've installed a Bosch DBW throttle body to the OEM intake manifold and am having problems maintaining AFR even with the wideband o2.  It will run extremely rich at idle and up to redline, but under load it will go extremely lean in the 20s and i'm essentially having to rev it over 4k and feather the clutch to get it up to speed.  I've read a few other threads of about the butterfly, it seems removing the vacuum to it is supposed to have it remain open, i've noticed no difference under 4k with the vacuum line to it plugged.  I'm hoping someone here has had luck using the NA manifold with Haltech, and if they happen to have a tune for it.

      Could it really happen......

      I don't know any details, but I really wouldn't be surprised if they do it as a LHD only version, at least initially.
