Another 1GGTE idle issue

[Rosie]

G'day all, I have a 1 ggte that has issues at idle ( idles a bit then cuts out). At aroung 3G it stumbles and coughs a little. I have checked AFM, Alternator, ISCV, Wiring, Air leaks, and most things suggested within other posts and all seems well.

Now I am only running a dump pipe at moment - is this the issue??, I havent played with turbos too much before and am unsure of the consequences of just running a dump. I have a surgey set up but no FPR ( not needed?).

And my last thought is new plugs? The spark is good underload but they were a little fouled - so they were just cleaned up ( pretty sure they were iridium ones too. It is throwing fault code 12 up but fks me if I can find that little post anywhere, any help would be great. Cheers Rosie, 281G.

thanks for the codes, just pulled dizzy out and checked all wiring - 0.04 v(seems very low for a signal) out of each of the four wires, and it won't run with the plug disconnected - therefore it is working?
Checked the starter signal circuit and there is 12V.

just windering if someone has an idea of what sort of signal im looking 4 out of the dizzy.

Also i have replaced the spark plugs (needed doing anyway), 456 seem good (firing deposits) but 123 are almost like they arent firing (Shiny new ish), I definitely have spark - injectors gone??

Just one more for yas - i have 2 plugs off the TPS, one small one with 2 wires ( whats this for) cant find it on wiring diagram and also the larger plug with 6? wires on it, where does the yellow with red stripe go??

Thanks for the help fellas

should be higher voltage on signals like about 5volt.
