reoccuring engine code p0356
I own and drive a 2004 Ford f150 Fx4, 5.4 3valve Triton. I recently just started having problems out of my truck throwing a reoccurring code for PO356. I've done everything to resolve the issues such as replacements of the Spark plug,Coil Pack,and replaced the Connector aswell. Went as far as changing my Temperature sensor and Camshaft position sensor cause originally I had codes that was showing they were faulted. After I Replaced them only for the Temperature sensor to stay on and now issue with the #6 PO356 code. There's no misfires. But I'm experiencing excessive motor vibration when I try to accelerate aswell as rumbling and power loss of acceleration. Any advice is greatly appreciated and thank you.

And just to be sure, the one you have been messing with is the second one back on the driver's side?
have you tried a noid light or test light to ensure the connector is good and is receiving the pulsed ground to the PCM?
The coil connector should have one side that's 12v with the ignition on, and the other side pulses to ground when the PCM commands it to fire.
It's easy to check for voltage one one side with a test light or multimeter and use a noid or test light to confirm the pulsed signal....
