Help figuring out Datamaster reading - stumble at idle
Hi Everyone
I am currently having an issue with my LT1 95 corvette where it seems to stumble while it is idling. I have taken a short datamaster logging with it sitting in the driveway while the problem was happening. Could any of you with more experience with datamaster and fuel injection take a look at this and let me know what you think? I have noticed two things... The IAC is sitting at zero while it idles toward the end and also the lines on the graph are a bit bumpy looking but maybe that is the stumble?
Thanks!
Ron

Yea, it took some time but I did figure out I had to turn that off. I am able to log just fine now and I had attached the log to the first post. I mostly just need help figuring out what is wrong with the car that is causing it to stumble while idling. For most part the only thing I see wrong is the fact that the IAC is at zero while idling toward the end.
Thanks!
