missing at idle
2009 lt 2.2
i have a problem, first let me say i do not have any codes coming up.
i makes it hard to fix this issue it seems to do it more often the missing
when i am trying to park (surging)
does my LT have a fuel filter and where is it now a filter clogged would do it all the time
last thing a air leak
all the codes that came lit i fixed

Why intake and exhaust SENSORS, not SOLENOIDS?
P0102,P0113, and P0172 are related to the MAF or it's wiring. And can cause P0300
Why change only 1 coil? Was P0353 after you switched coils in testing? Is that when the P0172 came up?
That sort of surging usually has something to do with forgetting to plug the MAF back in or not getting it plugged right. That does not always trigger a CEL.
Try some contact cleaner and dielectric on the MAF connector and inspect the plug.
