Random Misfire Across All Cylinders. Truly Random or Cause For Concern?
Well, was going to work after Ohio just got hit by a snowstorm. So, it was pretty frigid. Turned the car on, with the A/C already on full blast from the last trip in my car, and it had a big studder and almost stalled out. It held together though and a CEL popped on. Took it to Advance before work and I was stunned as he read off "Random misfire cylinder 1, random misfire cylinder 2...". He cleared it and was fine since then, but should it be something that can later turn into a problem or was it truly just random?

I don't like the sound of that... I forgot to mention as well, I have an EJ8 with a Mini - me'd Y7, compliments of the previous owner. I never trusted the engine, as I had to buy many sensors and work on it to get a CEL off when I bought it. First time I've ever seen that type of CEL on it though. For the past few months though, I've been getting a low threshold Cat CEL popping up randomly, think there's any connection?

Maybe the coil or ICM is starting to go. Maybe start by removing the distributor cap and inspecting the internals. How do the spark plugs look?

This could be sign of misfiring and a damaged cat.

The cat is killed by running rich, which generally results from misfiring. So while you don't have emission tests, it's wise to pay attention to the CEL.
Post pictures of the spark plugs, though you should just install basic NGKs as quickly as possibly. It also sounds like the rotor needs replacing.
Inside the distributor, look for anything abnormal - wear, corrosion, moisture, oil, dust - post pictures if necessary.

Re: Random Misfire Across All Cylinders. Truly Random or Cause For Concern?
So, I have a few things to report, been a little busy.
Put my OEM kit in, all my plugs looked pretty good to be honest. Still a small pop when it's warming up however.
Downshifted to pass a car today and got a code. Autozone dude read off Auxilary Emissions Control and Manufacturer Control, both laying under code P1456. He had no clue what it meant and the douche even forgot to clear it for me. My Cat is bad, I'm thinking it's just trying to tell me it again.
I think I need to replace my valve cover gasket. There are fresh oil stains down my block to my tranny and in that section of my cover, there is that squeeze - gasket poorly shoved into the gasket's crevases. Great.
I know my car needs a front alignment and new rear struts but it's walking worse than when Pujols is going to hit free agency. Is it all atributed to the alignment or do I have torn rear bushings? It's too cold to get on the ground and honestly, I'm afraid to look under my car to see the potential carnage.
Oh, and my battery is bad, so only really cold days, it's hit or miss if it'll start and my gauge and radio bottom out sometimes.
ISB is still grinding like a *****.
Oh and 94EG8 IS A MOD?! SWEEEEEEEEEEEEEEEEEEEEEEEEEEET.
Fricken' love my Honda right now.

Did you try a compression test? If not you should really look into doing on asap. from my prior issuse with random misfire codes. i found out that you should always try the cheapest soulution first before spending any money reaplacing any unnecessary parts that didnt need replaced to begin with with.

Haha, isn't it fun? Btw, if you need bushings and alignment, get the bushings first. Blown ISB bearings tend to go for a long time btw. Not that i'd want to put it off any longer than I had to, but they aren't as scary to me as they should be.

Um, my gas cap better not be missing. And I would assume it was fine...
Ah, I thought this pertained to my exhaust emissions. This pertains to fuel emissions...

Oh yeah. Full on lost my gas cap and it didn't even know about until today. Drove to AZ and grabbed one for $8. I then proceeded to pop the clutch in my parking spot. Today didn't start out too well considering I couldn't get gas after I got the cap, haha. Sucks being poor and going to school.
