Default 96 2.3L 'Chugging' Idle and High RPM to move

I don't know much about engines, although I try to do most of my maintenance myself.

For awhile, my idle has been "chugging"- revving up and down. Hasn't seemed to cause any issue with actually functioning so I haven't done anything about it.

However, now my truck seems to be requiring a lot of pressure on the gas, and high RPMs in order to start moving or accelerate from lower speeds. This is becoming an issue and I do not have any idea where to start looking for the cause. At first I thought it might be because part of the oil filter crushed when I tried to remove it (it is supposed to be good for 10k miles, so I ended up leaving it on since it wasn't punctured). I went to a jiffy lube and had them do an oil change since they could get it off- but that doesn't seem to be the problem.

Any ideas?

Have you noticed anything else and has this engine had any mods to it?

It's always had an issue with knocking when I go up steep inclines (a little Lucas in the oil usually makes that go away for awhile). And there is a rattle from the rear of the vehicle when I am at high RPMs, but I believe its from whatever bracket that holds the exhaust is a little loose.

Otherwise as far as I know its a stock 4cyl 2.3L 8 spark plug engine.

Well the first thing I think you should do is to clean the IAC valve and check for movement and see if the membrane is torn. Check for movement by , while the valve is in your hand, turn the key to run position and plug the valve in.

I ended up almost completely losing power to move today. I had a hunch that its the clutch, and took it in. They confirmed that the clutch is "burned up". They quoted $488 to repair, which is not going to happen when it looks like parts are under $150 (not paying $350 for labor, gotta be kidding me).

So now that I'm pretty sure that the clutch needs to be replaced- how difficult would this be for a novice to do?

The clutch can be a hand full. Getting the tranny off to get to it and getting to the clutch is about the hardest part. Once the tranny is off everything else pretty much slides out and back in. Just be sure that if you open it up for the clutch, have the slave cylinder replaced, more than likely the seals are getting worn pretty good if your clutch got burned up from the heat.

So it was definitely the clutch. Took me three days of work to change the clutch with the tools at hand (probably would have been much less if we had found the two hidden bolts at the very top of the transmission hours earlier).

Got the new clutch in, everything back together, and it runs great- much better than before. Problem is this slight grinding sound that starts when I change gear the first time and doesn't stop again till I stop. Then I found a small (about an 1.5 inches) bearing in the box that never got put in. The last thing I want to do is pull the tranny back off to get this bearing in- so how vital is this thing? If its just a matter of some noise and the clutch wearing out a little faster, fine I think I can live with that. But if its really important maybe i should take it to a mechanic and barter them into a reasonable price to pop this thing in?

That bearing could just make noise for a while or tear apart the slave cylinder, if you have the time, best bet would be to replace it now before too much wear happens on the clutch.
