I have a 2003 ford mustang v6 and when for the first couples months it drove fine but a couple weeks ago it’s been running fine when it’s cold but when the engine temperature reaches normal it’s rough idles when I’m at a stop and when I’m parked for more than a minute the rpm will drop and will want to stall and eventually will and there’s no check engine light or anything and after I will try to start it again and it will start for a second and shut right off. I cleaned the throttle body and air filter and idle air control valve. Still nothing. Please help:(
Wow! That's the classic sign of. It's running too. Rich and it's dripping too much gas so check the fuel pressure regulator first and see if any of the fuel injectors are leaking
I looked up the fuel pressure regulator and nothing pops up, maybe it only has the fuel pressure sensor? There is ones for the cobra Mach 1 etc but none for the standard v6
