Idle Relearn Process
http://www.sccoa.com/articles/computerrelearn.php Note: this is only for idle relearn. I personally had no luck doing it as stated therein. It wasen't until I removed the SPOUT connector did the computer accually adjust the engines air/fuel and idle speed. So, I recommend that you pull the SPOUT connector before you start the proceedure. Also, a minute is not long enough. While in park, drive, and neutral, watch the tach and vacuum gauges. When they settle into a constant spot, then you have it. Reconnect the SPOUT connector, and everything should remain the same, but now you have timming advance back.
There is also a relearn process for drivability or the car. After the idle relearn, you need to perform this proceedure as well. I had the information on how to do it when I was a member of
www.alldatadiy.com, but my subscription ran out recently. From what I can remember, you have to drive the car in a prescribed manner, and perform tasks with the brakes, transmission an so on. I think there's like 5 runs you have to do befor you're done. If I find my notes on it, I'll present them here, but more then likely, somebody out there has that information already posted somewhere. Personally, I just drive the car, but I really should do the relearn proceedure, as maybe I would get better gas milleage?
