This last weekend at my local grocery store parking lot and I went over some speed bump a little fast in my 1998 Dodge Ram 1500 with manual transmission. Once I got back on the main road I noticed in all gears I've lost all my go power. Once I get to about 3rd gear and 30 mph, I can push the petal to the floor without any acceleration. The motor revs up but no go. I've also noticed a louder than normal air sound when I push the gas pedal down.

Any suggestions where I should look first?

 

Well, just gonna throw this out there but maybe when you hit that bump it knocked the honey comb loose in the cat and possibly the sound you're hearing is back pressure from the cat since our manifolds normally leak pretty bad that'd explain the sound your hearing.

Also the cat can cause an extreme loss of power, try pulling your precat o2 and see if it clears up at all.

 

not a expert or anything but possible vacuum line disconnected...? its a good place to start

 

I got a good laugh from your thread title

 

Clutch? Love the title!

 

Sounds like a vacuum line popped off when you hit the bump.
I've hit speed bumps doing 40 before and they actually seemed smoother then when you hit them doing 4mph.

 

Will it rev and run ok when its not in gear?

 

Thats what my physics teacher in highschool told us, and i proved it many times in my stryker in Iraq. It was always fun doing 45 on a dirt tank trail over 2.5ft high speed bumps in a 22ton combat vech.

 

what he said.

 

I figure the reason is that when you are going fast enough then the springs compress and don't have enough time to flex back to their original shape and push the truck up before the wheels are back in their original position.

And I've heard about those heavy military vehicles being fun, a friend of mine got an lmtv airborne (completely off the ground) one time.
