Annoying intermittant power loss
Okay, this is really starting to bug me... this is the third '87 Accord
in a row now that's had this problem (all carbed, first had A/C and P/S, second P/S and non-working A/C, latest has neither. My first one was running great, really peppy, until I had a "fuel system service" done, and after that it seemed sluggish. Both of the subsequent cars have had the same issue: sometimes they're just "oomph-less" - bog down off the line, punching the gas accelerates only slowly, and pushing the clutch in for an upshift results in an immediate feeling of deceleration, almost as if something was dragging. And then for no apparent reason, often after idling for a couple minutes, like at a long stop light, the power is just there - sharp off the line, hitting the gas at cruise puts you back in the seat at just about any speed/RPM, and it keeps coasting smoothly when the clutch is lowered. I'd almost suspect a fuel delivery or ignition timing issue if it weren't for that "dragging" issue. I don't think it's the brakes; if they were sticking that badly they should be heating up as well, and they're not. Anyone got any thoughts? --- avast! Antivirus: Outbound message clean.

Re: Annoying intermittant power loss
I suggest you reconsider dismissing your idea of dragging brakes.
Sounds right to me. Next time this phenomenon occurs... I would wait until it happens several times and then pull over... and go around and feel all four brake rotors. Obviously you'd be looking for one (or more) that is hotter than the others. You certainly could have a caliper that is not releasing properly. I have seen this happen intermittently on more than several occations. Just a thought... Professor www.telstar-electronics.com |

All would be well after a restart. Problem turned out to be an intermittently clogged (nut & bolt catcher) screen at the fuel pump (tank) inlet.

Well... or sticky shoes on the back (drum brakes). I guess ideally I need to whip the thing up on a jack and make sure everything spins freely. --- avast! Antivirus: Outbound message clean.

Re: Annoying intermittant power loss
Matt
Had a similar problem with an '85 carburated, so here is one more idea(long-shot). Is there(or should be) a snorkel hose from the exahust manifold to the air cleaner in the '87?. If so make sure it's intact and in place, and that the blend air door in the air cleaner operates. in the '85 I had, the linkage form the blend door vacuum motor to the door got disconnected resulting in loss of power especially on humid days. |

The only recalls on this car are for the fuel filler tube rusting out, and the seatbelt buckles having broken plastic bits. If there were going to be a recall on this, it should have been issued a long time ago on a 20-year-old design. > In my case (and maybe or maybe not) your case it takes a long > time for a screen to rust and clog to the point where it can intermittently > effect fuel flow.

Nope. Low fuel flow and the float bowl not refilling would more likely manifest as sputtering and dropouts at high rpms. It doesn't do that at all - it's just an overall lost of acceleration power across the band. --- avast! Antivirus: Outbound message clean.

Not even in use on this car - it's disconnected and the breather lid flipped over to allow better breathing. Doesn't affect the issue. Hot or cold, damp or dry, doesn't matter - sometimes it'll run great right off the hop, sometimes sluggish at first and better later, sometimes it just never quite "wakes up". --- avast!

Re: Annoying intermittant power loss
For the heck of it I Goggled "intermittent power loss Honda". Got lots of
hits with many interesting reasons and causes. Some fuel pumps, rusted fuel filter, electrical (wires/plugs) etc. among them. A very hard one to find turned out to be the oxygen sensor. Quote from the write-up "Three days after the car first rolled in the shop, the problem was finally solved with a simple oxygen sensor replacement. Those darn intermittent." Suggest you try this path, might find your exact problem or at least something that will lead you to the solution.

The 1987 Accord most certainly does have an oxygen sensor. I thought so off the top of my head, because my recollection is that the oxygen sensor was a 1970s or so emissions control development (someone can google and nitpick away for details). www.slhonda.com 's parts site, under "exhaust manifold" confirms. This may not be thee solution to the intermittent power loss problem, but I wouldn't disregard it entirely, either, especially if the car is using the original, almost 20-year-old oxygen sensor. https://www.automedicsupply.com/ wants $32 + shipping for an OEM Denso sensor for the 87 Accord LX/DX. I used them for one a year or so ago. Good service. Best price for OEM by far. Packaging indicates this is a legit Denso sensor. Very easy to replace. Borrow an O2 sensor wrench from Autozone at no charge. |

Okay, put it this way: none of MY three 87 Accords have had oxygen sensors, including this one. Yes, I am quite sure about this, so don't tell me "Yes it does, you're just not looking hard enough." I got under the car with a Honda service tech while he told me where it SHOULD be on the first one, and there was nothing. When I finally went to another dealer service center, I was told by the service manager that most carb'd 87s DON'T have them. So there you have it. Given that the O2 sensor is supposed to measure the burn gasses and allow the ECU to compensate, I see little point in having once since there's no real way for the ECU to actually adjust the carb on these cars. --- avast!
