Well i got it.
Good luck
There's a JEGS fuel gauge under the hood thats reading right under 40 most of the time. I haven't pulled plugs yet.
Then we will know for sure we are not looking at the wrong area. Having to hold the pedal on the floor to start it is usually way too much fuel, but it's best to make sure. A black spark plug will tell us we are looking for the correct thing.
Thanks for the help.
The Best V8 Stories One Small Block at Time

Here's my IAC read out. This is right? I know it would have to allow air to get in to start up.

Here's the coolant temp? CLE is suppose to be CLT

Here's the LBL Left block lean, although I think it's at the Normal 128 reading because the battery gets disconnected alot.

Again I'm new to the scan master, hopefully pulling a plug tomorrow and seeing if they are causing my issue.
If we can see the color of one spark plug it will be a big help.
U need the DTC error codes. That scanmaster is giving u real time or capture data for whatever those abbreviations are - u need the scanmaster code book/instructions for those.
Sorry for the bad news but u still need a code reader to look at the PCM error codes - the PCM logs the error code history for u also.

Take a look at: http://www.fullthrottletech.com/atta...3&d=1135610183So that AES is really AtS = Air Temp = 53 degrees (chilly that day).
And IAC = Idle Air Control = 153 which is high out of spec.
Next is CLt = Coolant Temp = 43 degrees (burr, cold).
Then your last pic is LbL = Block Learn left = 128 which is term ECM learning (whatever that means).
Pretty cool stuff and it was fun to find it. And that scanmaster has DTC error codes too - just press the MODE button.

Hope this helps ya,

scanmaster is OK but kinda a toy compared to datamaster. Get a laptop and log it.
My rich problem that I chased forever turned out to be
one bad spark plug wire
one bad o2
Before that my plugs looked like yours and my oil smelled like fuel.
But plugs and 02. That was it. I thought all kinds of other things like programming, idle off, etc. etc. but it came down to leaking spark plug wires.
Good luck!
Side note no way I will ever get the last plug free from the drivers side, 3rd plug back with pacesetter long tubes. Didn't have this issue with hookers.
Replaces the 02s with new acdelco and almost 4 hours later started her up. Thing runs great and is nasty sounding

I need to fix yet another coolant line now but damn am I happy. Need tires still. It's currently running 7 autolite 104s
