Every winter, my Mustang seems to struggle with a rough idle, especially on those freezing cold mornings. It’s almost like the engine just doesn’t wanna wake up – the RPMs jump around for the first minute or so, and sometimes it feels like it's about to stall. Once it warms up, it’s mostly fine, but the start-up is rough every time it’s cold out. I've even noticed a slight drop in power during acceleration until the engine gets to a normal temperature. It’s frustrating because I don’t have this issue in warmer weather.
I’ve already tried a few things, but nothing seems to solve it completely. Changed the spark plugs last winter, but the issue came back again this year. I’ve cleaned the throttle body and checked for vacuum leaks – nothing obvious. I’ve also heard it could be something with the idle air control (IAC) valve or maybe a dirty MAF sensor, but I’m not sure if I’m heading in the right direction.
Anyone else had this problem with their Mustang? I’m trying to avoid throwing money at random parts or spending a fortune at the mechanic. Could it be a fuel issue, or am I missing something simple? Any tips or advice would be awesome – I’m starting to feel like I’m driving a lawnmower in the mornings!
