2004 f150 5.4 engine problems
 

I have a 2004 Ford f150 5.4L. When I was driving the engine light came and and started flashing and the truck started running rough. I took it to a ford dealership and they did a compression test. Cylinder #2 was only at 42PSI. They wrote on the work order. "road test verify celo runs rough/miss, scan tool pcm koeo P0171 P0300 P0302 P0316 P0352. KOER SAME CODES, PERFORM RELATIVE COMPRESSION TEST CONCERN WITH #2 CYLINDER 42% HAS BASE ENGINE CONCERN."
What does has base engine concern mean ? Is the engine done ?
