Rough Idle, Misfire, and shudder at ~3200-3800 RPM Codes P0183, P0303, P0193
My 2005 5.4 runs rough at idle and shudders hard between 3200-3800 RPM under acceleration. The following codes were pulled at Autozone-P0303, P0193, and P0183.
The P0303 says misfire on cylinder 3. I have replaced the coil, boot and injector and still get the same code. ????
