4.2 I6 intermitting stalling please see file Trailblazer Rainier

Hi;
Was hoping someone might not mind reading this file and giving there opinion.

My Sister has had a problem with a very intermittent stalling problem with her 04 Rainier/Trail blazer 114k miles. I figured I would try my HP tuners to see if I could see a problem. Here is a reading of it stalling.
It has:
Cleaned throttle body
New fuel pump
New variable cam sensor
new cam sensor

I am not familiar with these engines. The reading are with a hot engine. The timing looks odd to me. Any incite is very much appreciated.

Thank you,
Mike

Can anyone tell me if the readings look normal or can someone send me there readings so I can compare?
thanks

Does this look normal with the timing jumping around idling on a 4.2 I6?Attachment 46568

ideally you want smooth timing at idle but i couldnt really tell you if its normal or not on the I6. youll have to find someone with a properly working engine and have them log it to show you.
