That hiss is probably a leak in your brake booster. I had that on my 90 EX sedan when i would shut the car off. Does your brake pedal get instantly hard when you shut the car off on the first pump?

seem to have a bit of a delayed reaction, but the pedal wasn't too spongy. I chalked that up to bargain brake pads. Speaking of which, my neighbor brought over a bunch of new in the box Honda brake pads. These are the thickest brake pads I've ever seen.
Of note, the PO said he'd recently replaced the master cylinder. I have to get a pic of the wires leading to the master cylinder. It looks like he took an arm or leg from his least favorite G.I. Joe figure and melted it onto the connectors.Last edited by wtfisafleek; 09-19-2017, 10:31 AM.My '91 LX build. Bought September 2017. Sold June 2020.

I found a document that's been really helpful so far.
https://drive.google.com/file/d/0B7Q...ew?usp=sharing
I got to step 5; no vacuum leaks.
Restart the motor and go to step 9, per instructions.
When I unplug the IAC connector, the motor dies very quickly, not giving me a chance to check for vacuum. Should I assume it should stay running?
Losiracer, I did try pinching off the brake booster first, no change in the idle behavior was seen.Last edited by wtfisafleek; 09-20-2017, 01:40 PM.My '91 LX build. Bought September 2017. Sold June 2020.

So I went to try and see why the car won't keep running with the IAC disconnected, which may be because my base idle is incorrectly set.
So I go about doing that, but it's difficult due to the hunting idle. I pinch off vacuum hose #21 which eliminates this completely. What does this do? I think I need to eliminate this leak/incorrect signal before I proceed through the troubleshooting doc, but I'm not sure what it is, even when looking inside the control box.Last edited by wtfisafleek; 09-20-2017, 03:20 PM.My '91 LX build.

I thought I'd rule out the fast idle assembly. Here's what I found. A bunch of dirt mixed with wax:
Yuck.
Here's the bottom piece after I cleaned out the gunk. You can see the ridge of aluminum that helped make the wall for the o-ring to sit on has eroded away. I'm sure it wasn't leaking because of all the sediment clogging some part assembly. Looks like I need a new one. Anyone got a good spare? I may just block it off.

Picked up an A4/A6 header on ebay, ground some of the casting marks off, painted it with some silver VHT paint. I'm now waiting on a proper exhaust system to come in the mail.
I really wasn't going for a seamless blend, I really just wanted to knock down most of the sharp edges so they're not such an eyesore. Not to mention a little safer to handle.

Progress has been a bit slow lately with setbacks and I realize I didn't document them. So with that in mind, here's what's gone on the last couple of weeks.
1. Noticed the coolant had been leaking from my other car's coolant system, so I had to fix that, get it topped up, etc.
2. Cleaned the heck out of the front side of the motor. Man it was grimy. Those failed seals underneath the timing cover must've failed a LONG time ago. The motor looks to have halved it's age from 384K to about 190k miles.
3. Pulled and painted the windshield wiper arms a nice satin black. Replaced the blades, and replaced a broken clip that held the windshield wiper fluid tube to the hood.
4. Had windshield replaced.
5. Fitted a spare FITV and that's seemed to have cured my idle bogging!!
5. Received and fitted a full DNA exhaust system. This took forever to do properly because the header fit soooo bad. It's maybe a couple mm away from one of the A/C lines. So I wrapped it with DEI thermal wrap to protect that pipe. Not to mention I had to slice the crossmember and fold it back a little bit for the downpipe to fit. Finally I fired it up and...ugh, so loud. It was damn near as loud as my swiss cheese system was before, with it's myriad holes in the resonator, cat, and muffler. I took it off pretty quick.
6. Ordered a stock-type replacement system, still waiting on that. If it ends up being too quiet, there's always the Magnaflow catback I always hear so much about. Anyone ever heard of the MAC Parts system? It seems pretty complete, cat and all. I feel like I'm going out on a limb here, but if it ends up being a good system, it'll save me $200 versus having an exhaust shop do it.
https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1
7. Ordered and received a A4/A6 exahust manifold and smoothed it out a bit. This is such a pretty piece, it's a shame Honda chose to leave it in such a rough production state and cover it with heat shielding, because I think it would be very pretty if smoothed out and ceramic coated...
8. Wrapped the one A/C line with the deteriorating head shielding in a heat resistant braided wire wrap and secured it with some stainless ties. Looks much much better than the ratty look it had before.
9. Replaced my master cylinder cap with one from junkyard. Mine's wires were all gooped up with some black crap at the connectors. Looks like some kind of RTV or tar or something, I dunno. I inspected the copper underneath after I clipped it off and they were very green and corroded. Glad I changed it now.
10. Disassembled the rear passenger door to get the old window motor/regulator out. It was making these crunching sounds and judging by the gritty sludge around the cable entry point, I'm pretty sure some grit got into the gears inside and is eating them up. Need to get a new one there.
11. Disassembled the driver's door to investigate as the window rocks a bit back and forth and I think some clip that keeps it from doing so is broken. I think the rubber track could use some cleaning/greasing too. Is silicone spray the best method for this?
12. Got a made-to-fit sunshade. Man, these cars have a huge windshield compared to my other car. Outward visibility in these old Accords is outstanding.
13. Changed oil and filter, tranny fluid.Last edited by wtfisafleek; 10-10-2017, 11:32 AM.My '91 LX build. Bought September 2017. Sold June 2020.

Check my recent posts. I tried to disassemble mine last night to clean it, but it's like a house of cards. If you take it apart incorrectly, which is easy to do, it's not going to be worth your time to reassemble. New ones are like $50 from RockAuto, junkyard maybe half that.
It's probably just a better bet to get a new one to eliminate possibility of a quick failure. I can't even fool with mine because upon my first couple of tries to get it back together, one of the little springs took liftoff into the stratosphere never to be seen again. Super easy to get the assembly apart, impossible to get back together. I'm sure there's a way, but very difficult for me to figure out on the fly.My '91 LX build. Bought September 2017.

Just thought I'd throw in an update. Here's some pics of the DNA header I picked up off of Ebay. The fit was very bad in two places, so much that it took a lot of modding to even get to fit properly.
I covered it with some high temp exhaust wrap in hopes that it would give the A/C line enough heat protection, but in the end I decided it wasn't worth the risk of damaging the A/C system and ditched it in favor of the A4 manifold. You can see the number 1 pipe just doesn't cant over to the passenger side of the engine bay enough to give enough clearance to the A/C lines near it. Side by side with an A4(?) manifold really makes it obvious.
Little tip for wrapping, should you choose to try it: it's not difficult and you don't have to stretch it all that hard, you just have to be mindful to keep the tension on the wrap. So securing the piece in a vice or something to keep it anchored is really helpful.
I ended up grinding off the casting marks and some of the seams to smooth out the extremely rough surface. Plus it makes the silver paint pop a little bit more, IMO. I didn't totally smooth them out, just mostly knocked them down. It made it a little more comfortable to move around too.
How it looks as of last night:
Since I received my OE replacement type exhaust system (with cat) earlier today, I set about putting that on too. Everything went well until I got back to the muffler. It was way off. I'm not sure what vehicle it was made for, but the curve at the inlet pipe, the hangers' location, and the length of the tips was way off. This was a package I found on Amazon that was technically or an EX, but hey I have the dual port exit manifold, so I figured it would work.
So rather than fart around and wait another 2 weeks on these guys I ordered a Walker SoundFX muffler that should do the trick. I also conveniently forgot to order the tips, so I guess I'll have to grab some of those too.Last edited by wtfisafleek; 10-15-2017, 08:50 PM.My '91 LX build. Bought September 2017. Sold June 2020.

That's the thing; even after I got it installed, it didn't fit well, which is why I ditched it. I added a pic of the A4 header mounted just in case it wasn't clear where I'm currently at.
About the fitment, I also didn't mention that because of the #1 shape issue, it made it impossible to even put on without pulling 3 or 4 of the exhaust studs out. What a pain. Never again DNA, never again.My '91 LX build. Bought September 2017. Sold June 2020.
