misfiring evenlly and not randomaly?

Too much oil could foul up the spark plugs. Make sure the oil level is correct and then inspect the spark plugs. Might not have to replace anything.

^^^ When going up a hill in 1st, 2nd, gears the car accelerates and has ample power, but I can feel it sort of missing randomly. It doesn't feel like it's going to stall out, but something's not right. I'll check levels tonight before I leave work.

More than likely a misfiring spark plug, Monospaced is spot on, easy fix.

hit ^ broadcast to soon..
could be the coils to the plug or timing. if its same cylinder then maybe the cylinder itself... Usually you can notice performance issues using changing oils on old cars but it seems you have a new issue.
sound like you have leaking seals.. which is common for old cars...you never used those engine cleaner stuff? those degreasers can loosen seals and ruin coatings in the engine...
- No, never used engine cleaner. Had engine rebuilt last year - car is a total nightmare but I can't get rid of it.

spark plugs or coils would do that at any speed
maybe your transmission is fucked

The fact that the car seems to run ok until you need to give it the gas (IE up a hill) makes it sound like you're possibly running 1 cyl down and have a fouled plug (like Mono said). As a rule you should replace all of them and not just the one. They're only a couple of bucks and the job is relatively easy to do. Besides, you'll need to pull them one at a time to find the fouled one, so might as well freshen them all up.
Some tips: Get a spark plug wrench with an extension from your local auto parts store (long enough to reach down to the spark plug). Make sure you get the right one as there are 2 different plug sizes for cars. (You'll be buying new plugs while you're there and the guy at the counter can help you if you're not sure)
Also, do one at a time...pull the boot, remove the plug, replace with the new one and put the wire back on. You don't want to yank them all out and not remember which wire went where. (They need to go on in a particular firing order)
When you install the new plug don't gorilla tighten it. Just snug that baby til its slightly past hand tight. Too tight and you'll destroy the threads and you're boned.
I found a video showing someone doing it on your model - hope it helps.

Also while you're at the auto parts store buy some fuel injector cleaner and dump it in your gas tank. I like Chevron Techron. You could have some residue in your injectors and that could be why you're losing performance. Your injectors are basically little sprayers (think of them like those on a spray bottle) and they electronically meter fuel into the cylinders.

The guys who rebuilt your engine last year should be happy to throw in a free tune-up this soon after the repair.
- I never met a mechanic that would be "happy" to do anything for free. But wouldn't hurt to ask.GM278
- Rebuilds aren't cheap so they might throw it inGM278
- that's what I mean, they rebuilt it, they should at least maintain their fix for a few monthsmonospaced
- Totally. Wasn't a reflection on you - I meant I have friends who are mechanics...and money only goes one way with themGM278
- themGM278
- going to a mechanic is the most fucking stressful thing... especially since I can't do any of the work on these new carsmonospaced
- That' right there is why I own classic cars/bikes and do the work myself.GM278
- Yeah you heard what happened?

digital...yurimon - I had a '67 'stang and loved working on it. But I was definitely taken by mechanics on a Honda.monospaced
- I can't even get to the fucking gaskets on the HOnda without taking the whole engine apart!monospaced
- You need a whole shop to work on a modern car. The motor in my 69 VW comes out with 4 bolts.GM278
- I hear ya. Glad I don't drive anymore!monospaced
