r/Acura_RSX

I'm just curious, have any of you ever purchased a Chinese knock off upstream o2 sensor (234-9005) for your RSX Type-S and had it work properly? or basically anything that isn't a Denso for this sensor?

I have gambled with this too many times to count. When I get the ol P0134 on any of my k-series cars I think hmm maybe I can save a few bucks and buy the cheap knock off on amazon or ebay. It has NEVER worked for me.

Either the CEL comes on instantly, or I get some weird lurching behavior as the signal sent to the ECU glitches all over.

Never had this issue buying knock off downstream o2 sensors. Just curious about others experience with this. I always end up just buying the expensive Denso and it works. I just wish I could find an OEM equivalent that was not $150+

Recently replaced my downstream o2 sensor because of a CEL p0138 code, which fixed the CEL, but i have to do emissions soon, and my cat and eval tests are still in progress( blinking in photo) even after 100 miles driven after clearing the code. I’ve tried coasting at 55 mph on the highway, doing stop and go driving, what else does this damn ecu need to clear my tests???

Hey yall, I picked up this 06 base 5 speed about a year ago. Bought it at 140k miles for about 3k. It runs and drives but needs some work.
Rust in the floor pan (no issue for me to fix)
Needs a respray
General maintenance

The big question is if I really should commit to this car. I have the ability to do a k24 swap which is tempting, but im unsure if its worth it.

Part of me wants to fix what i need to fix, and slowly build it out. Another part wants to sell it and save up for a type s.

What would yall do? Any advice helps!

Hello all. Recently i have noticed that there is little to no resistance on the first half of my clutch travel and also my clutch has been getting stuck about halfway down as seen in this video. Any ideas as to what might be causing it and should it be addressed ASAP? The car has 260K miles and not sure if CMC or slave cylinder have been replaced. I’ve had the car for about 3 months and it is my first manual. Thanks in advance.

Picture of screw and where they go.

I bought a new pump and using the same hose but it’s not sitting flush. I try to push it hard but it’s still not sitting flush and when I tighten the bolt it kinda makes it worse. Any thought or tips ? It’s causing air to get inside since I’m still seeing bubbles in the pump

I have a 2006 Acura RSX Base automatic and I’m having a weird issue with the AC. I recently recharged the AC with R-134a last weekend because the AC wasn’t working properly.

Now whenever I turn the AC on, I hear a really noticeable noise coming from behind the dash. I’m honestly not even sure if I would describe it as a hissing sound or more of a grinding/buzzing type of noise. It’s hard to describe, so I attached a video so you guys can hear it for yourselves.

The noise starts when I turn the AC on and continues constantly while the AC is running. As soon as I turn the AC button off, the noise stops.
I can hear it pretty clearly from inside the car and it sounds like it’s coming from somewhere behind the dash, not from the engine bay.

What’s confusing me is that I just recharged the system last weekend. I’m wondering if this could be something with the expansion valve, evaporator, or possibly a refrigerant leak. I’m not sure if this is something normal that I’m just noticing now or if there’s actually something wrong with the system.

Has anyone with an RSX experienced a noise like this before? Does the video sound more like refrigerant/expansion valve noise or something mechanical?
I’m not planning on adding any more refrigerant until I figure out what’s going on.

Video attached for reference. Any ideas would be appreciated.

My rsx is throwing a air mix code on the climate control, i want to remove and clean my blend door actuator to see if that fixes my a/c

Hello everyone, long time owner, first time poster here. Having rebuilt a set of mono rs once and had them blow a second time, I am upgrading to something I hope to be more durable. I purchased the Progress CS3 set some of your suggestions, but am having trouble assembling the rear coilovers.

I am assembling them iaw the diagram but there is not enough room for the nuts to thread on, and it looks like there should be lots of room according to the photos I've seen. I have made sure the bushings are fully seated into the housing. Is there something I am missing or any tips from those who have assembled these before

I have a popped tired and I can’t take it off to repair it Cuse I lost the lug nuts key been looking for a key online and I can’t find any that looks like this
