so if i clear the memory it will still work aye like does that just clear all the codes that show

 

[detox_nath83]

yeah it just clears the codes... so if u clear it and then run a diagnostic again u will only have the faults display and not previous ones

how do you do these tests or where to start if your car isnt within specs 750 give or take at idle as thats what im trying to fix idling at 3 - 500 rpm

 

[lukee1986]

what do u mean by turn the ignition on and the voltage reading should be between 1.26V (lean) and 1.32V (rich). this is the base setting and if it is out then the AFM wont be able to be adjusted to a satisfactory mixture (meaning you need a new one)

and just for interests sake you can test the mixture by putting the probes on wire 1 and 3 with the key on and measuring the voltage. 3.6V is the factory setting which is lean, with 2.0V being rich.

so if i turn on ignition its goin to give me a ready of 1.2 1.32 but then you say to turn it on again or do u mean start the car as its confusing how can i turn it on twice and get 2 different readings

and by the way this info is copy and pasted out of gregory's hand book for vl give credit were credits due not taking the fact that it was p[roberly typed and put iin order so still alot of work involved
