I've got an 06 Eddie Bauer with 170,000 miles on it that seems to have a miss at start up when the engine is cold. I'm in central Florida so not actual cold but just if the engine has been off for a few hours.
After some internet research I was thinking it was a fuel pressure problem so I replaced the fuel pump which improved things but didn't completely solve it. Now my OBDII is showing a pending code of #5 cylinder misfire at startup and the exhaust is smelling rich. I'm not sure if this is fuel pressure related, spark related or injector trouble. OBDII shows stable fuel pressure until about 2700 rpms in park then it starts jumping all over the place.
Could the misfire be from a leaky injector or is it possible it's the fuel pressure regulator or fuel pressure drive module?
Also what's up with my erratic fuel pressure?
I'm new to working of Ford's (or anything with an OBDII and fuel injection for that matter). I've done a ton of digging but don't really understand all the info I've gathered. Any help or ejection would be much appreciated! Thanks.
