Every morning my car starts without a problem, but when I arrive at a location and turn it off, it sometimes won't start. When I shift gears at a stoplight, the idle sometimes drops too low, causing it to stall. I've already replaced the fuel pump, fuel filter, IAC valve, and battery. When I try to start the car with the windows fully up, and I keep trying to roll them up, the rpm drops.
Codes: P0156, P0141, P0136, P0161

Welcome to !

As I'm sure you can see, I've combined your 2 posts into one for simplicity. Someone more knowledgeable than I should be around soon to give you their advice. Best of luck!

XL-10 Motorcraft is mini vent lube for your window channel felts
Running that thick liquid silicone grease down into the window channel felts will LESSEN the NORMAL window slow operation
Pinpoint tests and an 03 PCED is where to start with the codes
Google each code first with a reference to your particular car
I'd do it for you, but you need the practice
A PCED is available at the library on AllData for free to print pages at most libraries
