Have you checked fuel pressure? Have you performed a tune up? Have you cleaned the IAC passage/throttle body? Have you filled up at a different station than usual or different grade of fuel? The O2 sensor is a reactive device, not a controlling device, so stop being so focused on it. Yes, the feed ...

when the idle is upset and in closed loop, what do BLM and INT values look like? BLM and INT showed around 128 both early on, later in drive BLM was a bit lower, and Red. When I started it I had a 2200 rpm idle, and the IAC at a level of around 90, later the idle was less annoyingly high, but still...

How can that be expected when rpms go up and down with it and gives a very unstable idle?

I now have a graph showing my O2 value running up and down between 80 and 800. It does that 10 times in 16 seconds from when it gets hot. When cold the O2 sensor reads very steady.

I'm not sure how to post the picture here...

What does it tell me?

In closed loop, that's how the O2 sensor should act. Yes, I've read that now, new to all this. But the article I read said it should cycle 5-7 times per second on a MFI engine. But mine cycles less than 1 time per second, and you can hear the engine going up and down with the change from RICH to LE...

Finally I'm connected and can see a bit about how it behaves. :D Thanks for the help Now the real problems start. I'm not sure what to look for, but I did notice that the O2 value was up and down in steady cycles, from 80 up to 1000, and further down it constantly switched between LEAN and RICH. I'v...

Google Chrome

Just tried Explorer, yes Save as Option. It suggested .htm, I changed to .adx, seems to work, look forward to trying it on car. Thanks so far...

Found an $A1 on these pages, can't download it though...

When I right click, I don't get the Save As option

Hi there, this is all new to me. I have two problems:
1. I can't connect. I have a USB ALDL cable, but the manual talks about COM ports only
2. I can't find a proper ADX file for my 1990 3.1 Beretta GT, only Buicks or 1991 and above

Any help will be appreciated
