stalling issue

[kindaflush]

hi all.
finally completed my manual conversion on my jzx100. it runs fine just sometimes coming up to lights it stalls, it seems to smoke when it is going to stall. if i nanner it, it sometimes goes to idle fine, but especially after coming down from higher revs it stalls. It has a atmos venting b.o.v, that ive tightened up, but didnt help at all. was on there before conversion also.
ive heard of people connecting wires to make it think its in 2nd, i havnt done this yet, if anyone can say if that will make a positive difference with anything will be great too.
thanks.

I had a similar issue on mine after the manual conversion. Adjust your idle up if you haven't yet, autos are factory set at like 600rpm and manuals at 800rpm iirc.

mine stalls from 1st cold start, idles real low 500rpm-ish or less and smokey (black smoke from over rich), will run like that for about 5 min then usually stall at the next lights

turn off motor, turn back on, instantly smoke is gone, idle back up to 800ish rpm, all normal. ive just gotten used to starting my car twice if from cold.

mine does that too.

apparently Manual ECU fixes it as the auto ecu idles too low.

from memory i think you have to put the ecu into limp mode or in diagnostic mode to re adjust the idle, as when you fiddle with it to get it how you want it, switch the car off and it goes back to normal

has with mine, just something i remember a mate at toyota telling me..........was half pissed at the time and may have completly miss herd him

have any of you manual folk crossed the wires to make it think its in 2nd? read somewhere that helps. had the mechanic change idle up today but havnt driven it since. if anyone has feedback on the tricking it into 2nd idea thatll be great. thanks

I've heard of people doing this too. There's info on the JZXWorld forums I think

o so this is a common issue, mine idles really low when warm too, thought my IACV was poked but maybe not, do let us know if you find a fix

My car hasnt stalled for over a year, not even when cold. After my conversion I gave that ICV a good clean out with degreaser/brakecleen/crc etc and raised the idle up to 800rpm. I am still running the factory bov though but also have a aftermarket one in the system which is done up pretty tight. I found without the factory bov hooked up my car would run rich as hell and reek of gas whenever I stopped at the lights.

I have read about the 2nd gear wire up as well but havent seen any solid proof of it changing anything - I think its just speculation?

i had the idle turned up and doesnt stall now, it seems to be idleing at 1000 to 1100 rpm when stoped for short periods, havnt tryed for longer, it does drop down to 900 or 800 when stopping, but jumps up again, ill try the 2nd gear trick and give some feedback in the next few days.
