Does anyone know of a link that gives step by step instructions on running this test? Tried searching for it but had no luck. thanks

 

find Joel5.0 then check for test proceedures

 

read here...long thread but pretty sure it's wht your looking for

Thanks that site looks like what i was looking for. Is buying a code reader worth it? I found this one on summit http://www.summitracing.com/parts/EQU-3145/

 

not really.... you can go to kragens, autozone etc and they do it for free

 

Adv AZ around here do OBD2 only. I usually read flashes of check engine light. That requires a piece of paper, pencil, jumper wire, and being able to count. Spend money saved on fuel.

 

yeah i got the same only have obdII's around here to. I ended up just ordering the one in that link but when I hooked it up to run the koeo, the fuel pump just ran the whole time and it didnt flash any codes. Anyone have any ideas why it would do this?

I did get the KOER test to run fine. I got code 41R which according to the book it says HEGO (HO2S) sensor voltage low/system lean. Can anyone explain this to me? thanks

 

Possible that is fuel related(injector on that bank is faulty), vacum leak, or faulty 02.
