so, a quick question for some of you mechanically inclined, with experience with this year/style engine.
2002-340. 6.2 mx engines.
Stbd engine was said to be freshly rebuilt when i bought. Both orginal 650 hours.
Both start idle perfectly. Run super smooth throughout rpm range.
However, full throttle, after warm up, port engine 5k rpm ish.
Stbd engine may hit 5k briefy but then gradually slows down to 3500.
No butps, farts, sneezes, just looses power. Havent changed anything except fuel/water seperator/ oil/ basic maintence.
This is my first mpi. Have service manual. Where to look first?
Thanks
