2003 Montero P0303

Scotty, great vids first of all. My 2003 Montero Limited 200,000 miles is throwing P0303 code after starting to rough idle and loss of acceleration. I did some research and found it could be a fruit basket of problems. Vacuum leak,  compression loss, dirty throttle body and AI sensor, MAP sensor, EGR, coil packs, etc. Please help! It’s been meticulously maintained and ran great until couple weeks ago.
