G'day

Today i pulled out the tfi dizzy and put a normal vacume advance dizzy back in.

Hooray, i finally have a stable idle and the car is now much more drivable. However i still have the afr all over the place

Now i think that the controller is the problem. I've changed all the settings to what there supposed to be so its either the sensor itself or the controller.

Cheers

hey elturbonitroso , i have almost the same problem as you have,

i havemt yet knocked my idle timming down yet but at the moment at idle my .xls file from the log recorder is up and down and up and down, it looks like a hacksaw blade's teeth.

and if i up the mixture it idles great but in the 12'S.

i have tried all sorts now and just on the chance of it i am going to replace the inlet manifold gasket on the chance it has a leak on it.
I will keep you posted m8.
