I'm honestly kind of laughing because the 9600X is actually a brand new AMD processor that just launched... are you sure your mechanic wasn't messing with you or maybe looking at the wrong tab on his computer?? But hey, this is a tech forum so I guess it fits! Anyway, I totally agree with the others saying don't just throw parts at it yet. I’ve been running Hondas into the ground for decades and honestly, the stock injectors are usually pretty bulletproof if you use decent gas. Before you spend your Black Friday budget on a 9600X (CPU or otherwise lol), I have to ask—is the misfire constant, or does it only happen right after a cold start in the morning? And have you noticed any weirdness with your fuel economy lately? If you're looking for long-term reliability, you really want to pinpoint if it's just carbon buildup on the intake valves, which is super common on these direct-injection engines once you hit that 150k mark. Basically, a thorough induction cleaning might save you a ton of cash compared to a full injector swap.

Hey! Misfires are the worst, especially when you need the car every day. I haven't personally used the 9600X, so I can't speak to that directly. But before dropping money on a new injector, might want to consider something I experienced a while back with my old beater, a 2008 Elantra. I had a similar misfire issue, and after plugs and coils, it turned out to be a vacuum leak!

My mechanic used a smoke machine to find it – cost me about $80 for the diagnostic, but saved me from unnecessarily replacing parts. Be careful though, some shops might try to upsell you after finding the leak. If it *is* a vacuum leak, the repair could be way cheaper than an injector. Also, make sure to check all the hoses around cylinder 1 for cracks or looseness. I would suggest doing this first before buying the injector. Let us know what the result is!

Hey there! I totally understand the frustration with a persistent misfire, especially when you rely on the car for your daily commute. While a new fuel injector *could* be the culprit, let's explore a slightly different angle before you commit to the 9600X, since that price can add up quickly.

Have you checked the valve clearances on cylinder 1? In my experience with similar Honda engines (though not *exactly* a Civic), tight valves can sometimes mimic a misfire, especially as the mileage creeps up. It's a relatively straightforward check, although it does require removing the valve cover. A shop might charge around $100-$150 just to check the clearances, but it could save you money in the long run if that's the root cause. If the clearances are off, adjusting them is usually cheaper than replacing an injector.

Also, have you considered a compression test? A low compression reading on cylinder 1 would point to a more serious issue like a valve problem or worn rings, which would definitely cause a misfire and wouldn't be solved by a new injector. A compression test usually costs around $50-$75.

Regarding the 9600X injector itself, I haven't personally used it. Before you buy *any* injector, make absolutely sure it's the correct flow rate and impedance for your specific engine. Using the wrong injector can cause more problems than it solves! Check the Honda parts website or a reputable online parts retailer to verify the correct part number for your Civic's fuel injector.

Finally, if you're still set on replacing the injector, RockAuto is often a good place to find competitive prices. Be sure to factor in shipping costs, and also consider that installing a fuel injector yourself can be a bit tricky, so factor in labor costs from a reliable shop if you're not comfortable doing it yourself.

Good luck, and let us know what you find! Hopefully, it's something simple!

Hey! Misfires are definitely a pain, especially when you're racking up miles like that. Instead of jumping straight to the 9600X (which, honestly, I've heard mixed reviews on – some say it's fine, others, not so much), have you considered a compression test? It's way cheaper than a fuel injector, usually around $50-$75 at most shops, and could pinpoint if you've got a bigger issue like a valve problem causing the misfire.

Unfortunately, I had issues with a similar misfire on my old Camry years ago. I threw parts at it for weeks before realizing the head gasket was leaking. A compression test would've saved me a ton of time and money. Plus, even if it *is* the injector, rockauto.com often has decent prices, sometimes even better than Black Friday deals, and a basic injector for your Civic might be cheaper than that 9600X upgrade. Worth a look! Let me know what the compression test results are if you go that route!

Hey there! I totally get the stress of a misfire, especially with that kind of commute. Everyone's suggesting the 9600X injector, and while more fuel *can* sometimes mask a problem, I'm always a little wary of chasing performance when reliability is the primary goal, especially with a cylinder 1 misfire.

Honestly, with 150k on the clock, have you considered a compression test? It's a relatively cheap diagnostic step that could reveal a bigger issue, like a burnt valve. A weak valve can cause a misfire that *mimics* a fuel injector problem. You can usually get a compression test done for under $100 at most shops. Knowing the compression numbers on each cylinder will give you a MUCH better picture of what's really going on.

I learned this the hard way back in '08 with my old Accord. I was chasing a similar misfire, throwing parts at it, and ended up with a $500 bill before realizing I had a leaky valve. Ended up needing a valve job, which was way more expensive than just diagnosing it correctly from the start!

Regarding your budget, maybe hold off on fancy injectors for now. RockAuto usually has OEM-spec injectors for Civics for around $50-$80 each. It's worth checking if they have a Black Friday sale. Getting a *reliable*, stock replacement might be a safer bet, especially if the compression is good. Plus, you'd have more money left over for labor or other potential issues.

Black Friday deals can be tempting, but don't compromise on safety. A reliable daily driver is priceless. Let us know what the compression test results are, and we can help you brainstorm more solutions! Good luck!

Hey! Misfires are a HUGE pain, especially on a daily driver. Everyone's kinda circling the 9600X, but let's pump the brakes and look at the bigger picture! While a slightly bigger injector *could* mask an issue, it's like putting a band-aid on a broken leg.

Honestly, I've been down this road with my old '98 Integra GSR (miss that car!). I was chasing a similar misfire and ended up swapping the injectors. I skipped the 9600X and went with a set of remanufactured OEM Honda injectors from RC Engineering. HUGE difference! They flow-match them, so you know each cylinder is getting the right amount of fuel. I think I paid around $250 for the set back then (about 5 years ago), which was less than one new aftermarket injector. I would HIGHLY recommend those! RC Engineering has a fantastic product and I felt like I was paying for quality.

Also, do a compression test. It's a simple check, but low compression on cylinder 1 DEFINITELY points to valve issues or piston ring problems, not fuel. A compression tester is like $30 at Harbor Freight. Better to spend $30 and know for sure!

Before you drop any more cash on parts, rule out other possibilities, like a vacuum leak on cylinder 1 or a wiring issue to that injector. It could save you a TON of money and headache. Good luck, and keep us posted! I'm happy to help troubleshoot further!
