    Sounds similar to my '98 many many moons ago when I spun a bearing at 225k

    The sound is completely gone now . The car is idling like it normally should. I can rev it in neutral to 3500 rpm's, but when it's in drive it won't go over 2500 RPMs and if I'm going up hills there is absolutely no power. It's almost as if the engine wants to make power but it just can't. The variables just keep changing.

    Did you check the oil to see if it's glittery?

    Your car has a rev limiter in neutral =3500, totally normal. No power up hills, lack of acceleration, bad mileage? Sounds like one of mine that had a clogged cat. Have you tried removing the upstream 02 (oxygen sensor) and then take it for a spin ? If the cat is clogged (like scotty said, think Beverly hills cop) exhaust pressure backs up and limits power. By removing sensor you'd create a new path for exhaust to flow (only for a short spin, not a fix) at least it might tell you where the problem is. Your 02 sensor is where you think it is, you mentioned it when you were working on plugs. Unfortunately, mine got so bad hot gas backed up and melted a hole through my plastic () upper intake manifold...extra costly.
    not what it looks like

    I will check the oil for metal. I've got a new pipe in order so hopefully that will help.

    The oil is not glittery. My downpipe should arrive tomorrow, but I'm afraid that won't fix the issue. I'm on the hunt for a vacuum leak because I hear hissing, and my MPG's are really bad, and absolutely no power when above 2k RPM. There's probably lots of issues, just trying to tackle them one at a time. But like I said, no glitter in the oil whatsoever. I can rev the engine in neutral pst 2k rpm, but the engine won't go past 2k when I'm driving. Also, the idle is around 600 or 700 rpm, but every few seconds it lowers a bit, then stabilizes. Probably just need to take it somewhere.

    If you rev once and let it drop down quick in a vid we could tell a little more. From the vid you posted, you don't need an exhaust pipe or to pull an o2. Motor is likely history from the sound I am hearing.

    But do that rev vid so we can confirm.

    There's an electronic throttle on those, like mine.

    I'm sorry, I had a link a long time ago for testing/repair. Having trouble finding it.

    in park open the door stick your foot on the gas pedal and reach around with the phone to the engine, then rev it to 2500 rpm and let the gas pedal drop, leaving the phone under the hood the whole time so we can hear it.

    or just lay the phone under the hood, we cant hear anything to well from inside the car.

    Motor sounds fine, no knocking or anything in that last video.

    The first ones with the loud tapping sound valve train to me, kinda half the speed as the crank with the clatter like a really loud lifter.

    FFDP - Would a bad lifter cause the issues I'm experiencing? It's getting worse every day it seems.

    It wouldn't make it this bad. If a lifter bit the dust it would for sure make a constant misfire on one cylinder and it would chug pretty hard everywhere. Check engine light would always be flashing and even with one lifter down it should still rev over 2,000rpm.

    You'd also likely get metal in the oil if it went really bad, it would start chewing the camshaft up or it could just break and bend a pushrod.

    Removing the exhaust is what I would be doing to rule that out, past that through video's I don't it's a rod bearing.

    This sounds pretty familiar. My 04 comp g chipped a piston, and the debris from the piston clogged the cat keeping it from going any faster than 3k rpms. Being that your oil is clean, your bearings are most likely fine. It's the piston that caused it. And depending on the size of the piston with expansion and contraction, that would cause it to either make noise or not.

    That's what I'm putting my money on anyways.

    ok, so to do that, I should remove the two bolts coming off the exhaust manifold(?) and remove whatever bolts are holding the rest of the pipe to the mufflers?
