My barometric pressure is 13.05 psi and Google translates it to 89.97 kpa.
what altitude are you at
About 3000 feet or a little more?

My wife's 6.0 tahoe has 82kpa. I noticed my maf air flow rate is in the 7s and the Tahoe is a 12. Maybe I should check my filter soon
Found a vacuum leak at where the oil fill tube(not sure the actual name) seats into the valve cover, and either the intake manifold gasket or the passenger valve cover couldn't tell for sure. Could this be causing the problem? A response would be well appreciated
My smoke machine I madeHow were these detected?
The hose is there. It was further back just didn't find a good pick from top side. Its somewhere from the middle to the back.The metal tube that's pointing forward should have another plastic tube attached to it that goes up to the intake resonator. It supplies fresh air to the PCV system. If you don't have a hose connected at the intake resonator, you will have unmetered air coming in past the MAF.
Yes but to no effect. I'm thinking it's either still my oil fill tube or my valve coverHave you tried using carb cleaner to track down the vacuum leak?
As far as the maf, map, etc goes they've been replaced and I was going off GMs parameters to set the codes and all readings are in spec to not set the code.you could be right BUT... you make the statement "with all my maf, map, etc working properly". You know that for sure?
Further related to your "premise" of pulling a vacuum line. Are you saying when you pull a vacuum line, you see a change in the vacuum being monitored? or you are just "proposing" that is what happens? Basically, what is your vacuum reading before you pull "any vacuum" and what is it there after?
but I think you misunderstand... especially related to your earlier post 198. The "conditions" that you were looking at, are operating parameters that have to exist for the test to run and set the DTC IF it exists. Those are NOT the conditions that set the code itself. I think that is what tjbaker was indicating.As far as the maf, map, etc goes they've been replaced and I was going off GMs parameters to set the codes and all readings are in spec to not set the code.
No to the vacuum reading but that's a good idea. I was just going on the thought process that if a vacuum leak was making it run rich then pulling a vacuum line would make the rich condition worse but instead my trims go more positive.
So it was the 29.8 at idle with the old throttle body and withI don't think so.... This is "key on, engine off" data. I think that the tb has a "relaxed" position and an enerigized position (ie. running). You can readily confirm by looking at the data at idle. You should see the tb sitting at in and around 20 for a "normal" idle. IF that is not the case, then perhaps you do have a TPS issue.
As for the fuel level, are you saying your tank is empty, half full, full and that indicator is not correct?
So with the old one it was 29.8 at idle, the spare one drops below 20. I just checked with key on and engine off and it sits at 30. I am going to compare it to the tahoe just for reference.I don't think so.... This is "key on, engine off" data. I think that the tb has a "relaxed" position and an enerigized position (ie. running).

I got a new phone so I lost all my data logs from car scanner, that was the last log i posted on this thread before that. I must have over looked the rpms because I'm grasping for straws here because I'm at such a loss. I do apologize for overlooking that. Do you have any idea what that absolute pedal E is? The only other thing I can even think to compare the two cars on is vacuum to see if there is much difference.I can't make sense of your posts which seem to be "broken up" a bit.
The post that you have attachments for and show the throttle position circled is not "at idle" but is just a key on. You seemed to then indicate that this was the "old one" at idle... ???? It is not IF that is the data attachment that you posted... the rpm on the engine is "0"... engine is not running.
Please confirm what you are seeing / doing.
