Engine going flat between 3-5k rpm

Thanks everyone for the response, it appears that it was a tank full of bad/contaminated gas............I added a bottle of "Gumout" injector cleaner and ran the tank down, fill'r up with Sonoco 93 octane (at my normal gas station, the last tank I was on the road and filled up at a 7-11)........runs like new... :dance: I will keep my fingers cross and monitor.........

I do have a follow up question/issue I would like to here comments on; K&N air filter...........I have been using one since the first service, I do clean it and recharge it every 5k miles, never had an issue..............but i've been reading alot of tech articles against using them, specifically K&N don't filter the particles small enough and it damages the MAF......I would almost bet that the people having problems just install them and forget about them.......the box does say 100,000 mile filter...lol

Thought/comments

Thanks Again
