4AGZE stalls?
|

When I accelerate then put clutch the revs drop and dont stop. Im not sure why this is happeneing .... I dont have the oxygen sensor in yet (installing friday).
The engine is standard the only mods I have done is pod filter, front mounted standard intercooler, ABV mod.
Anyone have any ideas what could be causing this?
Cheers
Andrew

mate mine does the same sometimes, dont know why either.
I hooked up the green wire from the computer to the brake circuit, which stopped it droping revs when i stopped at lights, but it didnt stop the occasional stall when i put the clutch in.
Is it Air flow or Map??

It may need a speed input. Heard of the same thing happening with some 1G engines. Fitting a speed sensor was the solution.

My next question is where do I get a speed sensor from and how do I install it? How much are they?
Any info you can give would help
Cheers

when I did my GZE conversion, the car did almost the same thing, I had some old plugs in it at the time, so changed them out with some new NGK's and the problem went away... My car has everything wired the same as a factory ae92 GTZ, as I used the complete set of looms from the GTZ, along with the dash etc so no wires were cut/spliced...
The front mount intercooler piping can also have an effect on the idle...

The thing is it idles perfect no fluctuation at all. The only thing is does is dies when I put the clutch in to stop.

not really all that helpful but my N14 pulsar used to do this. I never worked out why. Ended up selling it.

I had the same problem, with new spark plugs it went away, my idle was normal unless coming to a stop when you put the clutch in... then it would drop really low and almost stall...

What alternative is there for spark plugs for the 4agze? I dont want to have to spend shitloads on original plugs they are way to expensive.
Thanks guys

Just buy a normal plug of the same specs as the GZE ones - platinum plugs aren't really much cop, anyways.
As for the idle, what exactly does 'the ABV mod' consist of? My guess is something sloppy around there is causing you grief. Also be sure ALL the wires to the ECU (e.g. speed input) are hooked up, as you can't expect everything to work if you don't!

Could be your TPS (Throttle position sensor) wire or the sensor itself.
I had a similar problem and it was my idle up valve it was stuck on and ECU had tuned itself to idle around 700rpm with the idle up on and it would shudder at about 3-400 when it clicked off. I changed the idle up valve and reset / retuned the ECU and all's good now.

On the 12 pin plug on the ECU there should be a pin called the "ELS2", and another called "ELS1" (can be identified by taking off the top of the ECU, the board is labelled)
ELS1 = Stop lamp switch
ELS2 = Idle up diode
These both detect large electrical loads and compensate to the running of the engine by increasing RPM slightly (esp at idle). I would suggest getting these wired up if they are not already.
Also with the speed sensor, have a look at http://www.twincam.org in the FAQ section and have a look at the speed sensor mod someone did for their 20V. Looks easy as!
P.S. If you haev a GZE, why are you complaining about the cost of spark plugs?

OK I have wired up the ELS1 = Stop lamp switch (already connected)ELS2 = Idle up diode .... It increased the idle a touch but didnt really do anything about the car stalling when I put the clutch in.

when u did front mount did u modify any of the alloy pipes bolted to intake or throttle body section as some of these have fine ports for air
i know when fitted to ae86 they have to be turned 180 degrees and u loose these ports

Same problem here, AE92 AFM GZE with front mount and standard AE92 GZE ECU 
Anyone running an 86 with a GZE that DOESN'T have this problem? or if they did how did they fix it?

Dunno but I'm having the same prob with my 20v. Every time I put the clutch in it stalls. Gotta heel-toe every time I come to a set of lights or corner  Seems new plugs are the only proven solution so far, so I'll buy some new one's tomorrow and let you know what happens.

I did new plugs and such which improved the situation immensely, as did increasing the idle a little bit. I now occasionally have bouncing idle which i put down to a leaky ABV.

my 4agze done the same thing, had front mount and abv mod and nevo.
only ever died after hard on the throttle then quick off it then just wouldn't go to idle and stalled, i never worked it out, just got used to it by giving it a quick tap of the accelerator when i put the clutch in and it was enough to help.

Update, it happens more frequently to me if the car is under a heavier electrical load...ie headlights + stereo on. Earth leak?

Ok, I bought new plugs for it and, although it runs better, it did not fix the prob. So I went to see Dale last night and we went for a quick drive with the M/T handset in and it turned out to be the setting that controls fuel to keep it at idle after taking my foot off the accelerator. It was cutting the fuel almost completely (from what I gather) causing it to stall.
It's all good now! I guess this doesn't help you guys running stock ECU tho. I guess if you haven't already, change the plugs as this seems to have helped a lot of ppl.
Cheers,
Jeremy.

This isn't just a 4AGE problem, and it doesn't seem to be a fuel/air thing either. My 18RG has been doing it over the last couple weeks and i've tried everything mix-wise (forced air intake vs ramflos, high idle vs low idle etc). It's damn scary when you need to downshift on the highway and your car nearly dies while the clutch is in! Today i put in new spark plugs and replaced all the high tension leads (spark leads and coil to dizzy) and it seemed a lot smoother... Hopefully it'll stay that way. If it doesn't i think it'll be off to an electrician to replace all the leads around the battery and coil.

i had the problem with my 4agte, specialy since i have a atmo BOV. stalling out when comeing to a stop from too much fuel.
on the AFM there is a bypass screw, if you are stalling out from a exsessive rich mixture when coming off revs to a idle you can adjust the bypass screw to stop it.
it doesnt stall at all anymore.
i notice some of you say you have no 02 sensor, that makes the engine run rich too doesnt it?
