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...

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...

Newbie, not able to connect
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
