Hi Matt
I have just changed the diode and put it in the 12v hole as I did have it in the wrong hole.
I may have had a 1k resistor in R3 wrong as well as I am using the Edits unit.
Any way it’s really good news as after I generate an idle dutycycle curve 0 to 80 she started and runs really well and ...

Hi
Tried setting the idle control frequency to 320Hz and it’s still the same and I also tried another IAC and it’s still the same.

Can I just clarify the PWM idle connection on the DIY PNP with you to make sure I have them right?
I have the flyback diode in R5 one leg in the left hole and the ...

Hi
It’s a Ford iac valve as used on the Zetec and its set at 80Hz in the idle control.
I was having trouble getting the car to idle and tried adjusting it but this did not work.
I found out it was the 10 steps of the PWM idle dutycycle my car will not idle at 100 but is ok at 80.
Could I have ...

Hi
The problem I have is noise (I think) from my PWM idle valve (2 wires)
With the ignition switched on the Tps and coolant temp gauges on megatune jump around with air idle plugged in. As soon as I disconnect it they stop.
I have the flyback diode in ...
