My 2005 v6 mustang runs great in the warmer months until i drive it for about 30 minutes to an hour and shut it off, once try to start it up again after it’s been driven for a while it mainly stutters until it shuts down, but other times it will act like it’s either too rich or too lean and idle really low. This problem gets worse once it gets cool or cold out. I’ve replaced the crank and cam sensors, as well as 2 out of I believe 4 o2 sensors and the fuel pump but the problem still remains.
