Hello,
Recently my 2001 4.4i has been misfiring but only when cold. I keep reading codes and they all seem to be random misfires with fuel cutoff. I changed the spark plugs and installed new Bosch platinum plugs (figured it might be a good idea as the car has 122k miles) but this did not solve the issue. It misfires upon start up and when cold, but once the car is warmed up it runs fine. Can anyone help me pinpoint the problem?
Thanks
