Who can figure this out?

Yes, the wind resistance of the roof rack creates heat and smells hot. LOL
I will let you guys know before bed tonight, its still early on the West Coast.
I thought this would be fun for you guys, a nice little brain teaser.

Is it something to do with the intake? Seems like the MAF is blocked or something. The hot smell could be something stuck and burning. The bogged down feeling on the highway is something clogging the intake or somewhere along the line. The low rpms are due to the slowing down and less flow of air? No idea, just keeping it simple, thought I'd throw my 2 cents in.

can any of you read? He said 30$ 5 min fix. And KISS..
I thought about everything I could think about..
Belts cost 30$ and can burn and are easy to replace but shouldn't effect RPMS or driving speed.
Oil seperator hose would create a vaccume leak which could leak to idle problems. and oil getting on the engine and burning, BUT it doesn't cost 30$ or cause you to feel like your driving into a head wind.
Wheel barrings, could create a drag type feel AND burn AND cost 30$ but takes more than 5 mins to replace and dont mess with engine idle when coming off a ramp.

The coolant temp sensor was sending the wrong engine temp to the ECU so the ECU was dumping in to much fuel and basically flooding out the engine.
That was what was causing the "head wind" feeling and thats why it was almost stalling out when coming off the expressway.
It had to much fuel in the cylinders.
I figured this out by using my OBDII scanner with live data and watching the engine temp while driving to work.
The temp gauge runs off of a different sending unit.
The hot smell was the cats getting really hot from burning off all of the excess fuel.
The unit was sending temp readings of 100, 75, 175, 120, etc. Just random temps that were way to cold.
As we all know a cold engine needs more fuel than a hot one so the ECU was just dumping in fuel as fast as it could.
A cold engine running at 2500 rpm needs alot of fuel.
Because I paid attention to what my truck was telling me it did not run this way long enough to set a trouble code.
