Something isn't right..

Had a similar issues with a couple chevys lately.
18436572.
It happens.
Argued with my buddy, didnt want to recheck.
7/2 swapped.
Yes had it happen with the 5.7 before...
We've been around them a couple times...
I can tell you when the 5/7 was crossed I knew it wasn't running right in the driveway when I drive it up it would pop or get it going faster it would pop..
But I can start this car and it will idle and goose the gas and it has instant response and Revit to pass three grand and hold it and all is good...
Go to drive it and it goes into gear and holds its idle no problem back side of the driveway no problem gives it gas no problem starts giving it more gas and putting a heavy load on it and then it commits to popping and acting as if it's running out of gas... Hence the electric field pump and that didn't work...
Again with my customers a lot of times I just work once a week on their day off or something and we have an unlimited amount of time that they pay for. We try to go down the quick avenues without having to tear the engine apart. I'm not afraid to of course but are they willing to spend the money...
