Ran the scanner again today-no codes
The other day-code 34 was showing. Today, I disconnected the bat. before starting. Codes were OK all the way through. Ran her at 2800 for over 2 minutes as part of the trouble shooting-no code 34-good.
BLMs under idle 112 with a little throttle 128
TPS .49-good
MAT 92-93, have to look up
MAY 7.27 Grams-have to look up
MAF raw input 7-have to look up
Load variables (lV8) 50 same as above
IAC 106 steps-on startup
Knock Count 13-!!!!
MAP.94-on start up
AFR 15.31
Well, since I'm new to this-I've got alot to learn.
All digi displays are very close to scanner.
Your thoughts?? Thanks Guys. Hey, Ray, haven't ventured into anything else yet
but sooner or later I'll get there, just getting comfy. 
one step at a time.

Knock Counts are meaningless - you need to look at total advance and if any timing is being taken out. Know that the first time you approach WOT, it will advance until it knocks and then take some out.
Your BLM's at idle are rich and close to a Code 45 territory if they stay there with some throttle - less than another half volt from the TPS, speaking of which, you might try bumping it up to .54 or .56. Is the throttle body squeaky clean? Low TPS, dirty throttle body, misadjusted minimum air can sometimes produce a 34 and richen it up.

Your MAF at 7.27 gms/sec is in the right area for idle (7-12).
13 knock counts isn't so bad as long as you aren't pulling lots of timing.
MAT looks ok, especially if it wasn't that hot outside.
don't know what the MAP on start up is...you don't have a MAP sensor
MAF Raw is kind of meaningless, stick to the Gms/sec, that has meaning.
LV8 is engine load, that info is used along with vehicle speed, throttle position, coolant temp, MAF flow, etc, all to set up proper fueling.

Thanks guys, the throttle body is probably past due for a good cleaning, don't know if it has ever been cleaned,looks like I have another project, but I thought it was OK because of the plus or minus .08V. When I get time I'll clean the throttle body and adjust the TPS.
Actually I think it fluctuated .49-.51 thanks again.
