I have a 2003 Expedition 5.4L Triton. Two days ago, with low gas (38 miles to empty), engine started running rough. Code read P0302, misfire cyl. 2. Since it had 113K miles, I figured its time to change...


Most likely the coils. Easiest way to check is swap them with another cylinder, start it, pull the plug wire connecter and if it doesn't change the engine the coil is bad. If it is the injector, then you can check it with an ohm meter. Touch the leads in the injector it should read 11 to 15 ohms. if you need help let me know.

I have a 2000 model expedition and the codes po174 and po171 are popping up, along with po301 and po306 showing misfire. How can I fix that?


P0174/0171 are bank 1-2 running lean (insufficient fuel) which is related to the misfire codes. When there is a misfire detected, the computer shuts fuel to those cylinders triggering "too lean" codes. These vehicles are known for ignition coil failures. I'd recommend you replace all ignition coils (qty of 8) as they do have a short life span. Replace with another brand (not motorcraft/Ford), such as MSD/Accell/BOSH etc. hopefully this helpd!!

Oil pressure goes up for awhile and down for awhile.


I've not heard that a malfunctioning pvc valve could allow most ALL of your oil to leave the engine. The PVC replacement is a regular maintenance item over the lifetime of the vehicle. It is important to check your oil level regularly, like at every gas fillup. Could it be possible the engine was already very low on oil?

Obviously you should change out the pvc valve immediately, change the oil and filter in the vehicle and check the drained oil for metal scrapings and other signs of damage.

My final suggestion is that you have a trusted mechanic check it out.
