1ggze running rich, no idle controll

[1jzracing]

we just got a 1ggze conversion running in an old 22R corona but its running very rich and theres no idle controll,

it was running so high it was hitting over run fuel cut and surging up and down so we manually turned the stepper closed so it would idle bit it doesnt have any controll its just static, wont idle when its cold etc.

also its running really rich!

anyone had experience with the wiring ???

or is it more likely a faulty component??

thanks

Might be a faulty sensor?

I'm no standard management expert, but I'd tend to agree, a faulty sensor of sorts?

yea we tried a few temp sensor changes but no change, might make it rich but shouldnt affect the idle controll

have you checked that the stepper motor has power as it runs on a different circuit.
(happened to me on the first 1g i did years ago.)

thanks we havnt looked at that!

maybe all it is

still shouldnt be so rich, could be a totaly seperate problem

Check to see if the cold start injector isn't constantly working.
AFM could be playing up?
Is it running standard injectors?
Is it throwing any error codes?

thanks will check that out

how do you tell if it has error codes?

[1jzracing]

fixed

actually 2 seperate problems

it was the power supply to the stepper

and it had a cracked injector seal, vacuume leak playing havoc with the oxy sensor

funny how the hardest problems are sometimes the simplest things

runs a dream now

had that one sussed
