KCTSI

I just got done doing the above procedure... while my car idles better, i was curious of somthing..on step 4 KO you mentioned that if I stick the voltmeter to the green and black on the mps I should get 0.9volts... well I checked it twice and I got .4 volts... can you elaborate more on what I should check and what to replace if I need to.... The problem I am having is the car dosnt have the power it should especially uphills... could this be the cause? Any help would be very much appreciated as I have been tryiong to figure this out for a year now and so far no luck.... thanks again..
