Bogging? Or idling problem

I just did a tune up on my 97 prelude base, its been sitting through since beginning of the year, trying to get her ready to either be sold or start the project, she wasnt starting so i changed her wires and spark plugs and she started right up, took her for a spin she did good for the first hour, today took her for a spin she started overheating but not all the way i changed thermostat today bled her, now shes not overheating but now its bogging/ idles bad to point where after 5 mins of idling she dies i checked coils, battery, alternator all good. I think it may be a vacuum line or the iac valve but im not sure any thoughts. If you drive it its fine all thought in first gear from start sounds like it bogs and then catchs first.? All 5 gears are soild. When driving..

Any 6th gen owners actually put anyone in the back seat?

Hi all, I'm thinking about maybe pulling the trigger on a 2026 but am on the fence due to the rear seats. To be clear, I've personally sat in the backseat of one at 5'5". My takeaway was that I had to slouch a little to keep my head from touching the back glass which is obviously not ideal, but it would be doable in a pinch for a short drive. I do 99% driving alone but like to have the option of carpooling my friends occasionally.

I'm curious if any actual owners have had anyone in the back seats while driving. Is it manageable for shorter passengers or just too uncomfortable once the car starts moving?

Piston Questions

I’m rebuilding my Honda H22A4. As you can see, its sleeved, so the walls are a different material than the original FRM coating.

I was wondering if I could use oem/oem replacement pistons with different rings.

Forged pistons are also an option, but can I run them without a tune? I’m also worried about expansion size.

Just aiming for stock power numbers, and I have to stay untuned to keep ATTS, any advice helps!

Rear Steering Rods (Inner Joints) (4WS/UK/JDM)

I have tracked down a knocking noise from the Rear, to be my Rear Inner Tie/Track Rods. Can these be replaced separately to the 4WS unit?

If they can be, are they the same as the front inner rods?

Where can I get them from? I cant see them anywhere

Thanks in advance,
PFA

6th gen oil change?

My GF just hit 6k miles on her 2026 prelude. She asked me to do an oil change for her, but don’t see any videos yet online of how to do one. I got the manual so I can just read about it but I prefer the visual learning of YouTube. So does anyone know a video I can watch on how to do it?

Working on a 5-axis skeletonized shift knob design and trying to finalize the thread pitches. Would you guys run an aggressive billet setup like this in a manual interior?

Wanted an aggressive, aerospace-inspired look for my project car, so I engineered this skeletonized billet shift knob. What do you guys think of the mechanical aesthetic?

Wiper cowl / hinge cover struggles

For those that have removed and reinstalled the wiper cowl and hinge covers, is it possible to do without removing the hood?

I'm having a pickle of a time trying to get the cowl back on while the end pieces are on. I believe the end pieces have a tab that goes under the windshield trim/seal, but that doesn't seem possible with the hood/hinges in the way. Without the end pieces, I could get it on no problem, but there doesn't seem to be a good way to get the ends on when the cowl is pushed in to to the clip holders.

Photo for clarity (not my vehicle)

EDIT - Does anyone have a clear photo of the hinge area (with cover installed) with the hood closed?

Washer fluid hose connection

I've had my 2000 apart for too long. I have a washer fluid hose with no clear attachment point. In the picture above, I have arrows pointing to the hose as well as something in the hinge (which I thought was a drain).

Is the fluid connection inside the fender liner?

5th Gen Automatic Transmission Questions

Howdy! After years of searching for a mostly stock, not completely ratted out 5th Gen for my next project car, I finally found one near me that I am going to look at on Friday.

And before all of the "just get a manual", or "just do a manual swap" comments come in, listen, I hear you, I agree with you, but the price on this one for its condition is hard to pass up, so I'm at least going to go look at it and hopefully buy it if everything looks right.

The seller mentioned that the transmission is slipping, as these autos apparently tend to do. They said it is fine for a few miles, slips out, and won't re engage first unless you turn the car off and back on.

Not great, but that's enough for me to get it on to a trailer so not a deal breaker yet.

So, my question here from anyone who has experience with these automatics... Where should I start? From the research I have done it seems like drain the fluid, run new fluid for like 30 miles, drain again, and repeat 4 times is the key, at least as a starting point.

Otherwise, maybe replacing the solenoids?

The price is solid enough that if I need to drop a new transmission in it, so be it, but of course I would rather try and salvage the current one if at all possible. What would you guys recommend?

Headunit UI customization

Got a cheap Android Headunit on Amazon during Prime days. Spent the weekend setting it up to this point. I'm really digging it, and the live wallpaper was pieced together by me too.

Buddy's prelude blew up before getting it home

My friend just bought this 1998 prelude as his dream car and 10 miles from home the engine started knocking. This was after driving it almost 300 miles home too. He's stuck deciding if he wants to rebuild the engine, have a shop rebuild it, or swap in a remanned engine one. Any input would be a help. We're out in the St Louis area so any info on good shops would be nice.

Honda prelude 5th gen temp gauge reading weird

Hi all, just a quick question. My temp gauge on my Honda prelude 5th gen 1999 acts strange. It surges ever so slightly between the (bottom and top) lines on the little icon on the cluster. I have recently had the water pump and thermostat replaced from a mechanic shop. I have also personally checked that the coolant is bled correctly. Apon a small test drive the lower coolant hose is not getting as hot as the top. My thoughts is a dodgy or incorrect thermostat. Any advice?

(Picture for reference of minor surges) will go up and down within thoes lines whist driving every few minutes) also noticed the cooling fan was not running but fuses were good. Thanks

ISO ‘98 Prelude Parts

Searching for molding weather trim around the entire car. I’ve searched Honda Parts Now, Honda OEM, Honda Factory Parts… eBay seems to be my best bet but I’m a bit confused as it seems most of these door strips seem to be the bottom or bottom/side piece only. Has anyone had luck with this?
