'04 FX4 no power above 2K RPM
I'm new to the 5.4L modular engine. Mine has little to no power above 2K rpm and it turns over slow when cranking at operating temp., cranks fine cold. I had a blockage in the exhaust, that has been rectified, but still no ***** and hard to start hot. No codes. Any suggestions?
