for starters that was great right up <img src="/forums/images/graemlins/kewl.gif" alt="" /> , it shows that you got engine controls down. one quick fix. the O2 sensor senses Oxygen in the exhasut. when you are rich there is no oxygen, when you are lean there is an execess of O2 and the o2 sensor sends a variable signal from .2-.8V volts. to tell if it is goo or not get yourself a good multimeter(i perfer a good analgo for this because you can see the needle move realtime much better than the update rate of a digital.) and watch to see if it is constantly switching some where around .2-.8V (basically a high then low then high...) about 8 times in 10 seconds. if it doesn't roam at idle or it seams slow... then just replace it.

cant help you with the scan tool though.... maybe pay the 20 bucks or whatever to have a shop do it for ya.


if it does it when its cold only it sounds like it could be a dirty injector. some shops will properly clean an injector and you might be able to get a kit, if you want i can elabortae mroe.
