Accelerating issue

Ok, I need som ehelp diagnosing this issue. I just purchased a 2010 wrangler rubicon 2door with the manual transmission. It has about 30,000 miles on it, and until I bought it, it has never been wheeled at all.

That problem I started to notice was that when I was accelerating in like 2nd or 3rd gear, I would lose some power. It's a little hard to explain, but it's like I am holding down the gas pedal at the same amount of throttle and all of the sudden the jeep drops power and throttle and is not giving as mush power anymore. It still accelerates, but just less than it was before.

I am not letting off the throttle at all and I don't notice any change in the rpms or any change in the sound of the engine. Just less power.

Any ideas from anyone????

Does it happen at roughly 4000 rpms?
Jeep - It's a Jeep wouldn't understand.
Triumph - Go your own way.

I see why I'm a loner....and I love it!

I am not an expert but this might be an indication that the clutch is starting to go

If it's the clutch the RMP will increase as it's slipping but not put all the power to the wheels.

Starting with basics: Is the air filter fresh? Are the plugs clean/gapped? Are the plug wires/connections good? Fuel filter?
Does it feel like it wants to run hard but can't, or wants to die and you're goosing it?
