Been reading on WUE & ASE all evening and after tweaking un-tweeking and scratching my head, it still starts like a pig.
Annoyingly, if I hit the gas pedal as I am cranking it (as I do in most cars anyway) it starts within a second or so. The issue then is, I have to keep my foot on the pedal to keep it idling, if I lift my foot it drops to about 500RPM and stalls itself out running mega rich.
I 'tweaked' the ASE & WUE that much that my WB was showing AFR's in the 10's and the car stunk of fuel and was miss-firing, shaking like a sh****g dog.
I gave up to come inside and do more reading.
I have a feeling that it is all to do with this IAC valve that I cannot tune.
I have read THIS GUIDE
from MX5Nutz start to finish, which is a bit pointless as my car fails at the first hurdle.
I select Idle Control > PWM Valve >Open Loop Warm Up. Start the car, it idles anywhere between 2k & 4k RPM
I go to Test IAC - Steps =100 - Enable test, if it isn't already idling high it shoots up to 4000 RPM. I then start to walk down as told in the guide and by the time I get to 97 it drops down to idle between 1000 and 2000! WTF!? Therefore I can't find my values to plug in to the next settings table.
I have tried inverting the valve settings I have tried copying numbers of the internet but nada. Nothing seems to work.
Anyone got any advice? I may make a specific thread...
